Good tire math is width x 25.4 * 1.2 to get a max _reasonable_ tire width.
6" wants a 185 tire...I used to race 1st gen RX7s on that...
205 street will wander a lot on that wheel up front...same on the rear, but more notable between steering input, and the car doing something. And with the extra weight (side loading for cornering)...not ideal...but they look nice if you dont mind the tradeoffs
Sorry Stan, I am way dumb on this, I get most of what you are saying....I know the stock size for the phone dials, and I am happy with that size, when the kitty fills back up a bit, I’ll get new rubber for those wheels, and get them refinished.
I am quite happy with the rears on these wheels. The fronts are what confuse me. They actually look ok, but I do get a little wandering....to make these wheels a little more street friendly, would I need to go up a tire size or 2? Could I use 225/50 on these? Or am I backwards?
the 205’s look a little small, but not too bad, just want to improve the handling a bit.
hopemyou make it to SITM this year...I’ll buy you a beer or 2 and let you school me on tires...
I'm no expert but I can definitively say a worn out suspension is going to tramline all over the road regardless of tire combination. I had that issue and it didn't resolve until I replaced steering rack bushings and shocks.
Here's a tyre wheel calculator that seems to echo what others are saying...
I think you can put a bit wider rubber (than the calculator recommends) on the 6 and 7 inch wheels but longer term, you'll be happier with a 7 or 8 inch in front and 8 or 9 inch on the back. I'm a big fan of the 16x7 and 16x8 968 wheels as they can be found for a deal every now and then and they clean up/restore NICELY.
This set is available on Craigslist as of yesterday, for $250 OBO. The ad says one of them is plastidipped.
I bought a set of these for the same price in Jacksonville and painted them before putting factory sized tires on them 225 up front and 255 in the rear, I think.
Thanks Trey. The calculator will be very helpful. Can’t buy those wheels ATM....a bit tapped out. My buddy has piles of used tires, so I have quite a selection at hand to try out.
i only drove the car a few times prior to the master going out, but it didn’t wander on the 235,s like it is now on the 205’s.
once I refinish the phonies, I’ll most likely put those on this car with stock tires, and bump these to my 79 while I work on her.
#30 has restored wheels, and decent tires, but she is too original and I don’t want to start moving her parts around.
I'm searching for wheels for my 86.5 and just came across a set of Moda's
F=18x8.5 ET55
R=18x10 ET42
I am trying to use some of the wheel calculators but am not sure how these would fit - it appears the rear may stick out
Also, any thoughts on Moda quality and what you would pay for this used set ? (ignore the winter tires)
NOTE stock is ET 65 the most you would go up front is ET50.
For the rear stock is ET 65 the most you could go is ET45.
The lower the ET # the further away from the wheel mounting surface the rim edge will be.
Merlin - does this hold for 18" rims as well ?
Looking at 18x8.5 et 54 and 18x10 et 42 which fall out of this range
Why would you want to? Maybe a 245-255 with a 225...which really should be a 235 minimum.
The 'push' in that rear to front tire combo would be amazing.
They're a used set of wheels and tires. The fronts have to be replaced anyways so really it's just the wheels. Sorry, I should have just stated the wheel sizes but I just copied and pasted from the add.

Another tire and wheel question
