I know this topic has been discussed countless times and i tried a search but didn't get too far...

Currently on stock C4S/TT 18inch 'twists' and am getting an extremely good deal on a full set of new Bridgestone Potenza RE050As:
225/40/18- Fronts
295/35/18- Rears

Will this setup work or will i have diff/trans problems long term? I've read since the back is slightly 'taller' than the fronts i could have an issue...i know OE is 295/30 but will these be a big problem long term? Anyone running this setup? Tire gurus please let me know!

Thank You!

 

with 295-35-18, you're 4.7% over diameter. It's considered a lot for a car.

I'm surprised the 996tt has such small overall diameter wheels (25")

i run 25.6" on my modified '78 911...

anyway, 1-2% is ok but 4.7% is too much, i wouldnt recommend it, for various reasons.

 

Thanks Jon8..appreciate the info!

 

there's an awesome deal on Yokohama advan neova AD07 on Tirerack for 295-30-18 (closeout deal) it's one of the best tire available on the market.
