wheel diameter and tire availability

I'm struggling to decide on a wheel diameter to tuck under the 2" flares. I think 17's look really good on these cars and 18's might look just a touch too big. However, it seems that there's a wider selection of tires for the 18's than the 17's around the 275 width.

Browsing tirerack I only find a couple options for 275/40R17 but there are several more options at 275/35R18. For you guys running 17" wheels around 10" wide, what tires are you running?

I have 17x9 wheels- 295/40's on the rear and 275's on the front. Need more on the rear but not enough wheel width.
Looking back, I maybe should have gone to 18" wheels, but at the time I had no clue what would fit and even asking questions on every forum I could find, no body else had answers either.

On the '85 I have 17inch rims...9.5 wide in the front and 11 in the rear. You are right that it is hard to find tires in the 17inch size...and even harder to find matching ones for 2 different widths.

I have been pretty happy with the Sumitomo HTRZ tires. They are pretty inexpensive, and even if they wear faster, I can get 2 sets for less than the price of ones set of much more expensive Michelins or Goodyears, etc. I also get the Sumitomos at Tirerack.

BOTH!

I've totally ruled out 17" altogether, from a looks standpoint, AND from Tire size availability.

Lots of 18 " rubber around.

17" & 19" not so much, (with the caveat that the 19" stuff also gets really expensive).

Plus, you don't need offset trailing arms to do wider with 18's. Required for 17".

No Brainer.

18" all the way.

(18" & 19" staggered, if you're loaded $)

I'm using 17's on the front and 18's on the rear. In the picture it's a 275/40r18 tire on a 9.5" rim with a 5.25" backspace. This all fits within the factory fenders without rubbing.
I'm currently fitting 2" flares and using a 18x11" rim again with a 5.25" backspace. I'm hoping to fit 315/35r18 tires. It's going to be tight but I think they should fit!!!

Ok EASYGEAR.

18x9.5 on the rear, 17x8 on the front.

I'm still waiting for the 315/35r18 tires to come in. When they arrive I will post an updated picture with the 2" flares fitted.

Hi Mark,
There Toyo Proxes TQ's. There is very limited choice when using a 35 series tire. A lot more available with a 30 series profile, however I wanted a tire with a bit of sidewall (to match the front tires) and a diameter of about 26.5" to match the fender opening.

Running 18x9 in front and 18x10 in back. BF Goodrich g-Force T/A KDW 2 255 x 18 in front and 295 x 18 rear.

With the 2" flairs, street shop frame and C4 suspension there was room to go with 11" rims and a 305-315 tire in the rear. But ran into the same issue you are discovering. If you find the exact rims, tires are a problem. If you find the exact tires, rims are a problem.

that's a damn fine looking car

I think the amount of sidewall is key to making the 18's look right. With the 275/40R18's (26.7" diameter) it looks good. If anyone has a side shot of their car with 275/35R18's (25.6" diameter) I'd be interested to compare the two!
