My Michelin Pilot Sport ZR are practically gone on the front - say 40% in the middle and gradually going to ~0% on either tire side. Previous owner must have driven them under inflated. Tires on the back have more than 50% left and are in a very good shape - even ware.

So, I am considering changing the fronts only but with different brand - Goodyear F1 GS-D3. My questions:

* is there any drawback having different brands on back and front (Michelin and Goodyear), perhaps aesthetics?

* should I go from 225 width to 235 on the stock C32 rims, while I am at it?

Thanks

different tires front and back should'nt make a difference. only looks.
i'm running GS-D3s Front and discontinued GS-D2's rear.

if you want a wider tire, go for the 235, but when you change the rear, get a 255.

if you're commuting, it *shouldn't* be detectable....though if the compound
and traction differs greatly, you will experience some inconsistent traction
response...espec with widely differing treads during incliment wx conditions.
for the track, or road course, you should never do this unless you're fully
aware of the handling qualities of a given combination.

i wouldnt recommend using different tires. bcuz it will slightly affect ur performance. and also it will increase cabin noise.

235 on a 7.5" rim is too small. For that matter 225 on a 7.5 is a bit small. 225 on an 8 is ideal. 235 on an 8 is also sloppy at least with ps2's. Stay with 225

i had michelin pilot sports all round....
when the rears became worn i changed them to eagle f1's with a 255 width on stock rims and left the michelins on the front, so like you only in reverse.

I ran it like this for 6 months till the fronts needed replacing and had no probs whatsoever,
i then swapped the fronts for the goodyears and changed to 235's,

I have been this way for the past 2 years approx with the only issue being a slight rub at the front which occurs when i'm on full lock on a bumpy surface so no need to worry

Keep in mind that with two different tires they will have two different roll over rates. This shouldn't be a real issue during street driving, but at the limits this can be tricky. I have done it, with no problems, just be aware of it. You will notice it the most when you drive on a road with a high crown. The car will tend to dart back and forth because the each brand of tire will roll in its desired dircetion. Good luck.

Is that even legal? I thought all tire threads must match on street cars?? IMO, it could get dangous too in near limit situations. The grip difference could turn understeer into oversteer and vice-vesa...

On a 1986 Subaru, I'd say yes. On a modern, expensive, and highly engineered performance car like a C32, I'd say absolutely not. Maybe I'm **** but I'd buy four new (matching!) tires before going with a mismatch. I tend to think that tires are engineered to work together in fours and putting two different treads, compounds and heat characteristics on the car is going to have an impact on handling, wet weather performance and possibly gas mileage. All IMHO of course. I have friends who do this all the time and think nothing of it. I'm the resident party pooper on the subject.
