Rims and Tires for a 1971 Lemans Sport

All,

I need a wider tire for my Lemans Sport. I have been told I can put P255/60R15's on it and even 275/60R15's. Has anyone had any experience with this? I don't want to modify my fender wells for tires.

I'm not a gear head so please keep to the KISS method.

Thank you!

Tom G

I have had 245/60 14s on my 72 Lemans. There was still a lot of clearance in the wheel well.

I have 235/60x15 in the front and 245/60x15 in the rear. You make no mention of what you have now but if you have 235/60x15 the 255 is almost 1" wider and the 275 is almost 2" wider.

Melsg5,

I have P235/60's all around and my rims are 15 x 7 with a 6mm offset. The difference between 235's and 275's is only about 1.6" wider correct?

Thank you for all your input!

40mm/25.4"=1.6 correct
so that gives you .8 more on the outside and .8 more on the inside

I think I'm going to keep the 235/60/15 on the front and go with the 255/60/15 on the rear. I will let you know how it works out. Thank you,

just remember to check your speedometer accuracy with a phone app.
