hey guys this is the second time my front tires have done this....

they are falken fk452's 215/35/19 on a 19"x8.5" rim.... i know a mild stretch but nothing ridiculous.... do you think that the stretch would cause this to happen?? these tires have only like 2,000 miles on the front... both times it has happened on the inside of the tires... my front camber is like -1.2 maybe just too small of a sidewall to carry the weight with a small stretch and its causing the sidewalls to fail?? ive seen people run 225's on 9.5" you would think a 215 on a 8.5" isnt bad... are falkens know as poor stretching tires?



whats your guys take?

thanks!

Again tire problems dude??? Sorry to hear...IMHO it is the stretch...also possibly a flaw in the sidewall which is accentuated due to the stretch-no belts in this region as you well know...sorry I cant offer better advice...I also just replaced a tire after less than 2000mi due to a screw in the shoulder, so I feel your pain on this one

Stretched tires can lead to belt separation, sidewall splitting, bubbles, etc.
Also the tire only carries an 86 (OE93) load rating, so not much leeway when on the TL.

murph145

yea man its annoying second time this has happened i just replaced both front tires.... luckily americas tire was cool but i dont think they will be so cool this time.... and i cant run a 225 it would rub like mad!

damnnnnnnn

so the rating 86 is how much load it handles?? i had no idea about that.... do other tire companies with similar size (215/35) have a higher load capacity?

thanks!!!

Most are 85. Just some info, that 86 load rated tire equals 1060# less than the OE. The placard on the driver's door jamb specifies that total cargo+passengers not exceed 850#, which is to 80% of tire load capacity. In the case of the 86 load rated tires, the TL can have a total weight of 3738# (80% 4672), so hope you weigh fewer than 100# and have no additional weight in the car.

yeah i'm running falken 452's...i heard they were great stretch tires and that's why i bought them.

225/35/19's on 9.5" wheel...i've only had them on for a short while though, running -1.5 camber in the rear. i'll let you know if anything happens with mine.

stretching tires is bad, mmmmkay.

iTrader: (4)

this is just fuel for stretch tire haters. I hope you work it all out

murph145

so it seems like this tire just does not have the load rating as a wider tire would... a 215 on a 8.5" rim really isnt much of a stretch its a mild stretch but i guess it must be enough that when coupled with being on the TL it fails under pressure.... Now I have to figure out what to do because I got the tires from americas tire co and luckily the first time when both fronts failed they let me get new ones under certs but i wonder what they are going to do now.... and i doubt i will be able to run a 225 in the f ront being a +15 offset..... damn FML.....

Damn Murph, hope you get it all figured out. AT is usually cool, especially if you have a good customer relationship with them.

murph145

yea they are great guys over there they didnt hassel me last time but i think this time im guna try and run a 225 tire up front might have to raise the car 1/2" but it is what it is.....

i am also getting new rims in a few weeks they are on there way so i will have a different set up

BigPZ

What rims are you getting now????

murph145

^ ummmm Work VS-XX 19"x9.5" and 19"x10.5" +29

they are used i am taking them to a rim place over here that does repairs... I am having them re polished and touched up before i mount them should have them on the car in a few weeks

btw, what was your tire pressure in the 215?

murph145

^ haha they are at 37psi...??

falken fk452 are notorious for bubbling when stretched- might want to get some toyo t1r's

murph145

^ are they really? I was trying to search for issues but didnt really find much but these are not holding up at all!

not many manufacturers make a 215/35/19 tire

im guna go to americas tire co tomorrow see what they will do again...

causes:
Stretch
No proper maintenance (rotation/balancing/alignment)

murph145

well it cant be the later of the ones you mentionned they are brand spanking new less than 2,000 miles on them so its gota be stretch and load rating combined

really though a 215 on a 8.5" wide rim isnt bad i think its the load rating more than anything

swoosh

iTrader: (5)

^^^ thats a big amount of stretch....am running 235 on an 8.5" wide rim....215's are usually for 7"-7.5" topssss

SharksBreath

iTrader: (33)

well that sucks. i can't rotate mine ever bc 1) staggered setup and 2) directional tires.

fml.

they are properly balanced and i can get them aligned whenever i want to. TOE is set to 0.00 all the way around.

swoosh

iTrader: (5)

^^^ rotation is not as as as important as balancing and alignment....

i remember not doing any of those and my falken ziex 912 were done in 15K miles with threads showing up on the inside and bubbles on the outside

murph145

hmmmm so im stuck trying to figure out what to do... im guna stop by AT most likely tomorrow or Friday to see what they offer.... maybe i can talk them into another brand other than falkens for the front... id go a wider tire up front but i dont think that is possible unless i raise it a lil bit.... maybe ill do that im guna sell this set up anyways in the next month i just dont want a bubbled tire on there for the new buyer...

i wonder how much of a hard time AT will give me this time lol... im guna tell them that they shouldnt have sold me certs with the tires if they didnt expect this hahaha

SharksBreath

iTrader: (33)

murph, sorry to jack your thread...hope you get it squared away.

btw...i think i found wrenches... i'll be in touch!

swoosh, how often should i be getting an alignment? i have lifetime deal so it's free.

swoosh

iTrader: (5)

^^^ i get an alignment every time i do my oil change....it used to be 5K miles....now am at 7500 miles....

The reason I do this is coz I have lifetime alignment (a lot other people just get it done when they get new tires or something like that)

its not the stretch Falken FK452 suck monkey nuts, ive had 2 sets, and both sets have bubbled like crazy, i know about 2 others that ran them and had them bubble. i dont go near falken FK series

Ch33sE1

It's not that they suck, they are good tires if you run them with the correct rim size. 452's are not ment to be stretched because they have reinforced sidewalls. The cause of the bubbling is because the sidewall is so hard that if you try to stretch it, the wiring will snap and poke holes through the rubber causing the bubbles. I don't know where u guys heard 452's are good for stretching but that's completely false information. They're probably the worst tire to stretch. IMO go with Toyo T1R or T1 Sport, both of which are great tires I have used to stretch with no problems.

vipTL

iTrader: (2)

+1 on the Toyo's

When Falken first introduced the FK452 they advertised them on well fitted VIP cars, (remember the black GS with junction produce kit and and jp scaras)and most VIP guys stretch the living krap out of their tires to fit their wheels. FALSE adverting! lol

here is Proof here is my old modified mag from DEC 2007.

i've heard the 452 are great sticky tires but have a poor life. All the reviews i've read were from the non-streched users tho

I ran the falken 912 stretched without any problems! lasted until close to all thread being used up

update on tire situation, Justin?

murph145

Hey I thought this was dead lol.....

good info ch33sE1!!! totally makes sense!

Actually bubble hasnt gotten worse but I get my new free front tire put on tomorrow morning over at Americas Tire Center.... Those certs are worth every penny!!! They havent hassled me at all even though this is my third front tire to be replaced due to bubbles haha...

When I put my VS-XX's on in a few weeks the front already have Toyo T1's and I am going to put the same on the rear probably a 255/35/19 on a 10.5" rim... hopefully on the new set up no more issues tired of bubbles

my current reps will be for sale shortly

dope!

not to burst your bubble, but i've seen the toyo bubble too =x and it wasn't stretched

did you ever figure out what caused them to bubble? that happened with me and it was because the car had to be realigned...

Herblenny

My 2 cents on this topic...

1. my guess is that you saw bubbling on the outer rim and not inner? If this is the case, stretch or alignment has very minor reasons of bubbling.

Bubbling of the side walls happen because of some sort of impact that damages the sidewall of your tire. How this happens? Usually when you hit something that delivers all the pressure to one side of your tire in which side wall compresses to a point of either pinch or splits inside of your wall.

Some tires are softer and has less enforced sidewalls.. Of course sidewall design is very important for handling and ride quality and one brand/model will be different from one to another.

That being said, OP, your 215/35/19 on 8.5 I think is still under manufacturer's recommended wheel size for tire size. Its stretched (slightly) but I wouldn't consider as dangerous as stretched outside of manufacturer's recommendation.
If you continue to have this issue, I would consider maybe running run flat tires. I mainly say this because the run flats have much stronger sidewalls (no air and speed up to 55 - I've taken upto 80 for passing). And this means you might not be able to stretch it but I think your size should still come under recommended size.

**Issue with runflats are that some tire mounting machines can't mount that low profile tires. Make sure you goto places with top machines. I mainly goto places with Corgi machines. New Corgi's are totally touchless and mount and dismount runflats without an issue. Another issue with runflats is that they tends to ride bit stiffer**

ebelp

I can confirm this. I hit a large pothole @ 75mph and it put a nice little bubble in my side wall (stock size Bridgestones).

Herblenny

One more thing..

Lower profile tires tends to get 'pinched' more since less distance for the side wall to travel.. Usually two things will happen, you bend your rim or bubble your tires. To help reduce this, go with smaller wheel and taller tires.. I know this lowprofile fad started several years ago because of some high end car, but in reality, you reduce contact patch by going shorter tires with smaller wall..

from stock 235/45/17 vs. 215/35/19, at same tire pressure, my guess is that you now reduced your tire contact patch by less than 50%. And with increase in tire pressure, you probably reduced it another 5% (just a theoretical guess - true test will vary brand model and actual contact comparison).

Falkens stretch well, but bubble easily.
Tires that are stretched aren't the only ones that bubble. Square tires can bubble as well, it depends on the road conditions.
I chose to sport Nankangs for my new wheels, I hear they run narrow when stretched (woohoo!) and do not bubble as easily.
