Just what it says. How large a tire will fit, both on the wheels and under the rear fender of a late offset 951?

I am running 295/ 18's on the Rear of my 89.

ehall- Stock body, with maybe some minor fender rolling, will be a 295/30. 305/30 requires some more serious work.

The main issue is a bolt on the spring plate. Also, some cars have a kind of stiffening piece that needs ground down on anything bigger then 295. The spring plate bolt is the biggest issue, and the main reason mike (mpd47) fit 325 or 335 under his car ie because he has a kokeln torsion delete.

I'm going with speedlines eventually on custom offsets to squeeze 295/30's under my '87...

I run a 285/30/18 with plenty of room for 295's. No issues at all.

I am running 295/30/18 on the rears. The 295s are about as big as you can go bdefore you have to upsize your rims. I have spoken with different tire companies and they say you can put some 305s on them depending on the tire. Anything much larger on a 10" rim and you start losing tire performance.

Good luck.

good info. Thanks folks.

I believe you loose tire performance as soon as your an inch bigger than the rim

I've also heard that Hoosiers 315's have a narrower section width than the 305's, go figure. Think it was Jason Judd who said that. He got 315's under his 968 which I think was with stock guards.

295's no problem. 335's with torsion delete and aggressive grinding/pulling. Everyone above me pretty much summed it up.

What do you reckon on the fronts Mike? 285?

If you hit the "specs" page for any tire listed on tire rack they give actual tire widths and the rim range you can run it on. Very helpful if you want to compare the real size of one tire versus another - even with the same listed size.

That sounds like an Australian circumcision issue...from what I've heard from Aussie women.

275's are a good fit.

I ran a variety of 255/265/275's with Danno's guidance on the issue. You needed to cut the brake line mounting bracket off to fit 275's and have coilovers. (Obviously with smaller than stock springs). I bent a new brake line that moved it out of the potential for an impact with the tire.

Never tried 285's with stock bodywork. Have 295's right now, but it's wider.
