Tire Size Picture Comparison Thread

[tangerine911S]

Tires need replacing and Im not crazy about the size still on the car from the PO. They are 205/55-15's. Im looking to fill out the wheel wells with a larger diameter tire between what it is now and the large OE 185/70 VR15's. I know I may need to lower it a bit but I'm still looking for something a little larger.

What I would love to see are some pictures of different size tires on wheels. Im particulary interested in 15 inch wheel and 195-205/55-65 sizes but maybe this can be a reference for others as well.

I know someone is going to tell me to do a search but I searched long and hard and couldnt find what I was looking for (visuals). If I missed some good info or pictures please direct me to them.

Here is my '72S with the 205/55's that I am looking to replace. Maybe with 195/65 ???? Lets see some pics please!

squatted a little bit with a set of 205/55's looks real nice. I used to have a customer with a '70 911 S that had his setup like that. I wish I had pictures to share of it.

find someone to re-index those torsion bars and make that car look good! nice car man, it looks red in the pic... is it? Tangerine is pretty awesome too.

I just put 195/65's on the front and 205/65's on the rear of my 1970. I used this cool wheel/tire calculator to figure out what size to use:

Your car is beautiful, by the way.

205-60R-15 Pirelli-- ride height has a lot to do with it. But ride height must not be set at the sacrifice of corner balance or geometry.

[tangerine911S]

Thanks for the pics. My concern about 205's is that the sidewalls bulge on my 6" wheels so thats why I was thinking 195's.

Hester: Putting 195/65 in front and 205/60 in rear makes the front tire diameter bigger than the back (.75 cm i think). Is it odd to have such a combination? Do you have a profile picture to compare them?

Heres a pic of 195/65's all around and I really like it! 205/60 are slightly smaller diamerter but too pudgy? Opinions? I also love the ride height.

A 6" rim is within spec for a 205/60 tire.

The 195/65 should be slightly closer in revolutions per mile to the 185/70 the car would originally have had.

I don't have a profile picture but I'll work on getting one.

I used "195/65's on the front and 205/65's on the rear" (not 205/60). The circumference of the rear tire is 1.6 inches greater than the circumference of the front tire.

I have 205/60/13's on the 5 inch wheels on my CVCC. They bulge ridiculously! Hester has the 7 inch 911R wheels so the 205's are fine. The sidewall is pretty straight. 195's all around might work well for you. I think the idea is to keep the section width of the tire close to the wheel width.

Grady Clay suggested using a slightly wider tire in the rear to compensate for the 911's tendency for oversteer so that's what I did. I was coming off the freeway once when I had the 18 year-old 185/70's on, the LSD floated the rear, and the back end stepped way out. I countersteered like I was one of the Duke boys and got her back in line. That was a real wake up to 911 oversteer.

[tangerine911S]

Thanks for the good infro Hester. 195/65 front and 205/65 rear is definately a possibility. I was considering geting some 7" or maybe 7R wheels for the rear so that tire would fit well should I decide to sooner rather than later.

I have yet to experience the dreaded 911 oversteer. Ive never driven one on a track and dont drive agressively enough on the street I guess. Im sure its scary if you dont see it coming.

By the way Hester, you have a beautiful car and a great story so good luck with it.
