Tire Size - Clarification/Advice for running 4-16x7s
 

All

I am going to run 7x16 on all four corners on my 84 carrera cab. Ideally I would love a set of 8s, but that is low on the list for now. I am going to run a 1 inch spacer on the rear.

I have searched the forum and ran across a few posts where people did this. I saw folks with the 205/55 and 225/50 setup as if it was stock 6/7. I also saw someone who was running the 225/50 on all four corners.

I know that tire manufacture comes into play, I think I am setting in on the Dunlop Direzza Sport Z1 Star Spec. This car is only a street car, does not do track or DE. Right now it is set to stock US height, and I don't want to get into rolling fenders.

What tire size would you recommend? I like the appeal of running the same size on all four corners.

Thanks

I'd use 205/55 & 225/50

Thanks for the input...

I agree with Bill.

Some times it can be a little bit of a chalange to fit a 225's on a 7" rim up front unless you have a rolled fender and have maxed your neg camber.

Other than that there is no reasion you could not run all 225's on a street car.

Porsche ran a square set up on there street cars for years. The biggest advantage is you would then be able to rotate your tires front to rear for a longer tire life.

As to performance, modern 911's have mostly understeer dialed in as much as it possable so having a 225 up front will help with understear a little. It might also reduce stopping distances a little.

However, where the 911 needs more tire is in the rear if one wants to increase performance potental.

I had the Star Specs and loved them. Great tire.
