And yet again another tire question!

I know the subject has been covered and I have searched to see if there are any previous posts but I want to ask to see if there are any new thoughts (it's a shot).

I have a 1975 911S and the factory tires were 185 70 15. Should I step up to 195 65 15 or 205 65 15 tires? The car is mainly stock and is never driven on the track or in the rain.

Second question. Was there a tire size for the rear different thatn the front? Should I stick to this if so or should they all be the same size.

I know you are all sick of this questions but any response would be appreciated.

I run 195 60 15's on my 74 911. I think they look good and result in lowering the car nearly an inch re: the 70's with no suspension modifications. I personally think the 205 60's look a little pinched on 6" rims.

I would definitely use the same size tires all around.

The tire size was the same for front and back. 205/50s all the way around should be a nice tire. I assume that you have 6" or 7" wheels.

Have a friend with a '73 who runs that set up on 7x15s all around and he has no rubbing issues. Cars do vary slightly though.

I have the 205 60 15's on now and I agree. They do look a bit "pinched".

Do you have a picture of the 195's on your car?

The wheel size is 6".

I currently do not have any rubbing with the 205 60 15 tires so I would assume the 205 50 15's would be OK just a bit shorter (by 20 mm or so) and still would have tat "pinched" look as 74-911 suggests.

That being said the 205's are snug fit!

RE: pics of 195 60 15's on 6" Fuchs.
It's been raining all day so these are the best I can get.

I have a '74 911 with Fuchs 7jx15 wheels. I'm running Dunlop Sport 9000's in 215/50/15 on the rears and 205/50/15 on the fronts with no rubbing, problems, etc... Stock suspension, daily driver in nice weather, no track driving...

How do the 215/50/15's look? Are the tires bulging from the rim? Any pics?

If you're running 6x15's on a street car I'd go with 195/65's.
They will be the same height as the original 185/70 so will maintain gearing and speedometer accuracy. You will gain a little rubber on the road and they will fill the wheel wells.

205/50's will fit but will be too short. The speedometer will be wrong and they'll look too small in the wheel wells.

One of my cars had 205/50/15's when I bought it. All the above was true but on the other hand it sure spun up fast! On the freeway I could have used another gear. Running high rpm's and burning lots of gas with those little tires... go with 195/65. If you just have to go wider then 205/60's will also fit.

Thanks for the comments Bob.

I currently have the 205/60's but i wanted to see if there were any opinions onthe width. I think I may try the 195/65's.
