Interesting info on Vredestein tires by Ebay seller. He quoted some nice info from an overseas mag called "Powercar". .http://cgi.ebay.com/ebaymotors/315-35-20-Vredestein-Ultrac-Sessanta-SUV-Tires-ZR-110Y-/140571195117?pt=Motors_Car_Truck_Parts_Accessories&hash=item20bab236ed#ht_7372wt_1165 ..
I really like my Vreds, but I want a wider rear tire and do not really like the 315/35/20 Vreds because the 35% sidewall is too narrow. I want something 295 or bigger but want to keep 40% as sidewall height because I like a lot of tire showing in the rear. I will run a 245/40/20 in the front for a nice muscle car look, that can still "turn" when it needs to.
Look into the tire height and not necessarily the #. I have 315/35/20's now and they have just as much sidewall as my 275/40/20's did.
I really like the Vreds on my Charger and highly recommend them. Here is a pic from the rear. PS: That ain't me on the trailer!!
depending on the make of the tire also. lol the Vreds are like the nittos. they are a tad smaller than what they say they are.
Lol, I know my NT05s only come with 7/32" of tread new (instead of the normal 10/32"). Maybe that's why
I wonder if that's all of it. 3/32" less tread amounts to almost 0.2" less height. You said 29" and the calculation comes to 29.29"... In any event I don't think there are any specifications or standards for taking tire measurements. Rim size is rim size, sidewall height is % of tread width. I'm guessing how you determine treadwidth is open to interpretation. If the tread to sidewall was a perfectly square 90* angle it would be pretty clear. With rounded shoulders and wrap around treads one manufacturer might measure it slightly different than another and maybe even differently from one tire model to another? Naturally they have to be close or you'd have a lot of unhappy customers when they didn't fit but I suspect it's not all that standardized?
