sup guys, as some of you guys know, im running 235/35 up front and 255/35 in the rear. however, im rubbing a lot in the rear right now, partially because im only at -1.1 camber. im thinking of downsizing my rear to 245/35/19, lowering it a bit to close the gap it will create, and add a bit more camber. here's a side view



1. do you think i should change the size? looks a bit off that the rear is so beefy, but the front is slightly stretched lol

2. if i do change from 255 to 245, how much gap will i increase? im worried that if i lower the back to close up that gap, i'll get that reverse rack going on, where the back is lower than the front lol

thanks guys

 

ummm seeing as your staying with a 35 series your not going to loose height but you will get a little more stretch maybe the stretch might make you think you have more gap but the tire should stay the same i would assume. im sure someone will tell me if i wrong but thats what i think.

 

hmm cuz i thought the 35 is in respect to the side wall ratio, so if my side wall gets smaller, even though im staying at 35 series it will ultimately be a bit shorter as well?

someone correct me as well haha. but thank you odus for the help appreciate it!

 

Any reason why you can't run 235 in the back as well? besides the fact that our rear wheels sit 'more sunk' in the rear? I'm a big advocate of the correct stagger tire setup as defined by the vehicles drivetrain and/or the same size front/rear. Besides enhancing the appearance of your vehicle, I don't see a benefit from a functionality standpoint.

I guess logically, if you wanted to do it correctly, you'd run a wider wheel/tire combo in the front and less wide wheel/tire combo in the rear with obviously the appropriate offsets to get the look you want.

and to answer your questions:

1. I'd go with the same size in the front. Camber settings do magical things in terms of how the wheel/tire setup looks in your wheel well. In the photo, your rear tires look hella big.

2. Moving from 255 to 245, you'll see a .1 inch size difference. Well, maybe you won't really notice a .1 inch size difference, but that's the difference going from 255 to 245 LOL.

tire size defined (broad view):

235/35r18

235 = section width of tire
35 = aspect ratio of the section width of tire (35% of the section width)
18 = wheel size

Odus, when i first got into cars and learned about tires, I always that the middle number remained the same size sidewall regardless of section width and wheel size. I was wrong LOL

Good luck, Ed. If i had 19in, I'd probably run 245/35 all around. If I was running a reverse stagger (correct stagger on FWD), I'd probably run 10in with 285/30r19 or 245/35 in front and 8.5in, maybe 9in in back with a 225/40 or 235/35 and the correct offsets to make them look appropriate on the car.

Sorry, information overload...

 

so changing the width but keeping same aspect ratio witch is how tall the sidewall is can change the sidewall? im confused more pyro hahaha

 

correct, The sidewall number is simply a percentage of the width. So 35% of 245 is less overall than 35% of 255. Its not going to be a huge difference but is a difference. Oh and the difference between 255 and 245 is 10 millimeters NOT .1 of an inch.

 

You sir are correct than it will be a bit shorter. see above post

 

Actually, I was referring to the aspect ratio or 'series' difference, not the section width. Sorry for the confusion.

 

thanks guys!

and to be honest Protoype, your information helps a lot, so don't feel bad at overloading on info! haha

i didn't want to stick with 235/35 in the rear because i have much more room in the back. im not a fan of that super stretch look, hence why i went with 255 in the first place. just didn't realize how big it is compared to 235. now i want to switch to 245/35 so it wont look at beefy, and it'll match the front a little bit more

and yeah i understand the whole reverse staggered for FWD, but i ultimately chose the "look" route over function

thanks guys for the responds!

 

This continually needs reiteration because people don't "get it."

The 18 is a fixed number. It is the bead diameter of the wheel being used.

The 235/245/255 etc is a fixed number and is the width of the tire tread when mounted on the correctly sized wheel.

The 35 is NOT a fixed number and is the height of the sidewall expressed as a percentage of the tire width as described before. In this case the sidewall height is 35% of the 235/245/255.

Your overall diameter should always be close to the overall diameter of the stock tire (225/50/17) and your front/rear diameters should be nearly identical.

 

Eddie'O Be a ballah and run 275/35 in the rear like me To be honest, I think your cheapest and most effective solution is to dial in more negative camber.. Try -2.0 in the rear and see that works. If you still rub like hell, then down size the tire to a 245/35.

 

camber them in lol and run -4.5 like me hahhaha
no honestly 245/35 will give you more room and when you lower it a bit its gonna look even

 

This, Ed!! I completely overlooked your current camber settings!! -1.1 is nothing DOOD! move it to -2.0!!! You should have plenty of clearance on the inside.

 

but it'll still look un-proportional though right?

 

245/35 and play with the camber dial it to -1.5/2. Unless just do the camber first with the same tire your running and go from there, alignment will be cheaper then Buying two tires.

 

Roll those fenders I have 255/40/18 9 1/2 wide 35 offset with megan street coil overs Im tucked about one inch on the rear with adjustable rear arms and 1.2 deg camber they rubbed bad before rolling fenders now zero rub even with my three kids in the back seat thats about 250 lbs and it looks much better rolled and tucked a little bit

 

Oh forgot see how youre rear wheel is pushed back the controll arm kit with all 3 arms will let you pull wheel forward so it does not hit the rear bumper flange in the wheel well that is were mine rubbed the worst before changing arms

 

i ran out of breathe reading your post LOl

my fenders are shaved already lol


i think as of now, i might just lower a bit more and dial in some camber...change tires when these run out.

 

THe guys at the local tire place were wondering why I was hellbent on running a wider tire...they kept saying it'll kill clearance and weigh more. It's true...and with our rather torqueless cars I'd say that running a little narrower is probably best.

 

Sorry Ive been a mechanic for 30 years and I specialize in run on sentences and miss spelled words

 

Well, who the hell needs punctuation when you have 30 years of knowledge about ANYTHING!?!?

Carry on, sir!

 

alright guys..i lowered my rear and dial in almost -4 camber on both side...im rubbing like CRAZY.

i lowered my rear too much

my rear tires are too beefy.

i lowered another .75"







question:

im gonna raise the car by at least .5", after that would 245/35 clear? or should i just stick with 235/35/19's?

 

bump

 

go to 215 you punk

 

well you 9.5 all around just staggered offset so why not going with 235 all around

 

Like tobwac said I'd prob just go 235 all around, also where did you take that pic it looks hella familiar

 

Be a man and go 275s!

 

yeah i think 235's will be what it is...and ben i can not fit 275's LOl

and 215 is wayyyyy to stretched for what i want

 

where you rub most at that dam tab?

 

Oh, the endless quest to find the perfect stance for daily driving. Good choice on the -4 camber though. I am at -4 as well

 

not sure, my tabs are shaved lol. my fender is pretty much sitting on the tires right now though...

 

so you completely deleted that tab where bumper and panel are connected?

maybe try different stiffness setting

 

LOl does it? cuz that's my garage bro

 

the first pic with the stairs lol not your garage xD

 

ohh LOl. that was at UCR

 

oh lol! nvm about that then never seen it in my life

 

235s all around!

 

Took A quick look almost thought it was a new Cadillac lol
Look Tight!


thanks guys [/QUOTE]

 

picked up a pair of 235's for 100 bucks. michilen ps2, time to mount it tomorrow

 

shoulda ran 215's wit me xD
