My 95 Bonne SE needs some new shoes. Normally not an issue but I noticed the previous owner had 205/70/15'* installed. Stock size is 215/65/15 on the SE. Since I'm not really well versed in the differences is there any advantage to running the 205/70/15'* vs. the stock size?

From what I know the one'* I have now are narrower and taller than stock, but is there really any advantage to it for a DD? These are the steel rims if it matters.

They were probably cheaper, but I'm surprised the shop installed such tall and narrow tires on a boat such as a Bonneville. Go with the factory spec. You have more tread on the ground and your not susceptible to roll off the bead because your CG is up higher.

Moved to Wheels and Tires for better visibility.

your talking 10mm difference in width and hardly any difference in height. not likely going to notice any difference, so if its a size that cheaper or easier to find in the brand you want, i would say either is fine. much more important is matching is the type and brand of tire to what you want it to do

My PA is factory spec'ed at 205/70R15. I have seen both sizes out there. Either size is fine.

I also believe in running a tire pressure that works too. I believe GM recommendation is 30 psi, which is another joke. I try to do 40 in front (tires rated to 44psi) and 35 in the rear.

My car has 205/70R15 stock too. It'* much cheaper than a 215/65R15 because its a more common tire. There'* very minor differences in the overall size, so I don't really see any problem running them. Some shops might not install them on your car though, because it isn't what the car calls for.
