You could fit a 205/225 set up, or maybe even a 195/215. Your wheels are a little narrow so the 225's could be a little ballooned but it'd still work.

7" wheels with 215s I think will rub on a narrow body. I think I'd go with 205/60s front & back.

My narrow body 71 911T gets a little bit of rubbing (front
The choices for tires in a 205/55-16 are nearly endless

In my opinion (does not show up so much in photos) the 50 series tires look sort of like golf cart tires as they do not fill out the wheel wells. You would have to lower the car an awful lot to conceal this. Here is mine with both. 50 series 15" ![]() Golf-cart like. 60 series 15" ![]() Need to roll rear fenders now because of width not height.

205/50 x 15's will work fine. 215/50 x 15's may or may not work at the rear... you'll have to fit them

Probably the 215's won't work but you may get lucky.

My 74 has the stock Fuchs
If the additional inch of width is to the inside, you may get a larger tire to fit. good luck, chris |

205's all around.
As noted, 225s will rub in the rear, depending on ride height, camber The challenge with regular 911 7" wheels is that the additional width is towards the OUTSIDE of the car, The only 7"s that really fit, are the 911R wheels with their 49mm offset. Even then, you may get some rubbing on the oil lines on the right side. My folks ran 911R wheels with 225/50-15s The only other modern wheel porsche makes that comes close is the "late offset" 7x15 phone dial from a 87+ 944. These had a 52.3mm offset. If the motor is stock (ie, 160hp), you really don't need more than 205 (which is 8" of rubber) especially considering how much tire technology has improved since the "then new" 185 tires that the car came with. 50 series tires will certainly "waken up" the acceleration of the car with the sacrifice of top speed.

![]() This photo is with the 205/60-15 on 7 inch fuch rims. ![]() ![]() The 60 give a fuller look if the car has not been lowered. The 50s make the car even lower to the ground but work just fine.

I have 7Jx16 Fuchs on the front of my car. 205/55-16 Yokohama Advan A048s. No problems. I have fiberglass fenders, so no rolling. The only thing is that on the driver side, the corner of the bumper where it meets the fender was just brushing the tire shoulder when pulling lots of lateral Gs in a right turn with a lot of steering lock on. A little filing cured that. I have heard of people having similar issues with steel panels. It seems that side is tighter than the other for some reason.
