Pauly Posted 1September, 2017 Report Share Posted 1September, 2017 I have a small situation. I need new tyres, and i'm going Yokohama Advan AD08Rs. 245/40 R18 on a 8.5" and 285/30 R18 on a 10" wheel. But they dont have any 285 30 R18 in the country for the next 2 months! so only option is going 295.. Is that a little big? Theres no 275 and 265 is to small as i've got a 265 on the 10" already. Thanks! Link to comment Share on other sites More sharing options...

Pork Chops Posted 1September, 2017 Report Share Posted 1September, 2017 I ran a 295/35 A050 on a 10" rim last weekend on a Boxster. No worries at all. Front is 235/40 and is 8.5. Link to comment Share on other sites More sharing options...

Pork Chops Posted 1September, 2017 Report Share Posted 1September, 2017 How did you go with sidewall movement? thats my worry.I know they fit, im worried about side wall movement. over size tyre on a rim. From the driver seat it was perfect. The car was flawless to drive. Theoretically a 295 is too large for a 10" rim but felt fine to me. I also run a 295/35 on a 10" rim on the Carrera S and it's obviously a bit too big in that application but I like the look and no adverse affects felt. In any case seems to me you don't have an option. Link to comment Share on other sites More sharing options...

TrevMcRev Posted 1September, 2017 Report Share Posted 1September, 2017 I had 295 on 10 on the rear of the 996. Still did good burnouts and donuts so you should be right! Link to comment Share on other sites More sharing options...
Avon Posted 5September, 2017 Report Share Posted 5September, 2017 Yes they will fit, slight bulge but I ran that size tyre and rim for 18 months with no issues. Its good you are upping the front widths too to keep it balanced - I didn't and felt the extra 30mm on the rear contributed to understeer. Link to comment Share on other sites More sharing options...
Kammo Posted 7September, 2017 Report Share Posted 7September, 2017 You do get exaggerated sidewall flex and the shape of the contact patch is a little different. It's not noticeable 99% of the time but your car will drive differently on the limit. When I purchased my car the previous owner gave me his track tyres and the fronts were 245 on an 8-inch. When I switched to 235s on a 9-inch there was way more front-end grip and I had to back the rear sway bar off, but this only became apparent at the track and I was totally expecting more understeer from dropping the front tyre width relative to the rear.
