Tire Size vs. Wheel Width ?

Like I said , I agree with all the above posts , but they are radials and have flexable sidewalls to start with, letting a little extra air out of them to get the contact patch flat on the ground aint that big a deal. " If ur not trying to make a corner carver out of it "------
I`m thinking seriously about putting the 295 60 15 d.r. back on my 68 fastback, cant find anything much better (bigger) that I can get under it, being non tubbed. Really would like to have sticky tread tho. Been looking at 295 60 d15 hoosier quick times, but don't think the sidewalls would clear, as they are wider than my 295 drag radials.

Yeah, if you're not trying to make a corner carver out of it, I guess you have a few more options. I believe that drag radials in particular are more accommodating to playing with the tire pressure...though I've never owned a set so I'm just going on what I've been told.

Otherwise, you might be ok for accelerating and braking but if you need to steer hard, you're certainly going to notice those squirming tires.

Why not spend a few bucks and get wheels that can take advantage of the extra surface area?
