HELP identify 1968 wheel and tire size

Hey all,



My 68 came with the American Racing AR105M Torq Thrust M 17's and I wanted to identify which size it is. I'm thinking of going with wider front and rear wheels. Car is being rebuilt now so don't have access to it. Took a photo of one of the tires.



Any chance someone can identify the size? attaching sizing below from their website and my wheels.











My second option is to purchase the Forgeline GA3 Perf Series in Satin Black,
Size: 18x9.5 & 18x12

I've seen customers running 245/40/18 & 335/30/18

What other tire options can i go with? Any chance someone knows a good website that ships tires internationally? Much appreciated

Re: HELP identify 1968 wheel and tire size

You're running the same tires I have on my 68 - 235/45R17s -mine are on 17x9 rims. Any tires larger than 235s will run into clearance problems with the original offset. You can simply measure them but the backspace they list doesn't look right. A 0 offset should center the wheel on the hub, so an 8 inch rim should have 4 inch backspace, not 4.5". That's the issue I have with mine since I swapped out my original 10 bolt and lowered my car. My 0 offset rims pushed the rear tires out too far. I'm switching to a positive offset of 25-30mm. That will take up most of the inside clearance I have and give me room between the tire and fender. The 18x12 rims you suggested won't fit without installing mini-tubs. The 245s might fit up front but it will depend on how low the car sits and the offset you're using. Check tirerack.com - they might ship internationally, but I would expect it will be expensive regardless of who you find.

Thanks for the feedback. The specs i attached was from the website so it looks like they have 2 versions of this wheel

So my backspace is probably a 4 , correct? Im keeping the ride height as is, just going to correct the right side since its sitting a little higher from the left
