Hi,

I need to replace 2 tires on my 2005 Acura TL (had 2 replaced a few months ago due to flats). Instead of the OEM tires, I want to put in BFGoodrich g-Force™ Sport. If I put 2 new g-Force tires on the rear axle and leave the 2 OEM (Michelin Pilot MXM4s) tires on the rear, will it cause any problems, specially with ABS and VSA.

The specs on the two types of the tires are :

OEM (MXM4):

Section Width:
9.6"
Aspect Ratio:
45
Measuring Rim Width:
8
Rim Width Range:
7.5" - 9"
Overall Diameter:
25.6"
Tread Depth:
9/32"
Revolutions Per Mile:
814 (at 45 mph)

g-Force :

Section Width:
9.3"
Aspect Ratio:
45
Measuring Rim Width:
8
Rim Width Range:
7.5" - 9"
Overall Diameter:
25.3"
Tread Depth:
10/32"
Revolutions Per Mile:
797 (at 45 mph)

Thanks

As long as all 4 tires are the SAME exact size, there shouldn't be any problems.

Just some advice...put the new tires on the front. There won't be any VSA or ABS problems, but the car might not drive straight, due to the different tread designs of the tires. DEFINITELY get your wheels aligned.

The tires have have the same size 235/45R17, but they do have slightly diff overall diameter (25.6" vs 25.3") and diff revolutions per mile (814 vs 797). Do these differences matter?

Princelybug: can you please elaborate? Did you mean that the car may not drive straight with the new tires in the rear? Or that it won't drive straight with the mixed tires period?

Thanks.

The car definitely won't drive straight with new tires in the rear, due to the fact that the car is FWD. But even with the new wheels up front, there is a great chance that the car won't drive straight.

sorry bug- this one you are off on the facts
ASK any tire store
ALWAYS put the BEST tires- most tread on the rear of any car, FWD included
What happens in a rain or low traction situation is you want traction in the back- or the rear end can lock up and come whipping around to meet the front and pass you into the turn
Not drive straight on the freeway? what?
You get more problems with that by rotating the tires, and causing internal belts that have been coasting and going straight,,, to pulling turning and braking- that causes problems

That's why the guy at the tire store said they always put the new tires on the rear. You got me. I was confused. I was wrong.

ur best bet is to replace all 4... buy hazard protection, and keep the 2 good stocks for future flats....

ps. mix tires... you will feel it... also will create poor handling

princely: you were not wrong~ just confused which end- thats better than not knowing there is something you are supposed to do! And you have a good tire shop- they know to do it--not everyone does.

mixing tires being a huge issue is from back when you could purchase the modern radial tire (steel belts) or the old school Bias-Ply (nylon belts) tires
That would screw up your handling like you cant believe- or ever care to drive!!!

Today, if you can get a tread pattern close to the same, thats good enough for this situation. Dont take it to the race track or drive at double the freeway speed limit, but for everyday driving --just drive it
Tire shops sell 2 tires all the time- often a better brand for less $ than what the car came with...like the mickeyslips on the TL
If it was that big a hazard to mix brands they would not do it--too many customer complaints cause big headaches

Oh- dont put different brands or models left and right on the front- that would be really bad!!! Those tires need to match each other
As a mechanic from the old days- I have driven many cars with mixed tires- sometimes each one being different! and never crashed any of them.
