17x8 Ultra Type 62 +10et (4.9" bs) w/ 265/70/17 Duratracs. No rubbing, cutting, anything on stock suspension. 5100's set at .85 now and still no rubbing, cutting, or anything. I've tested both setups at full lock both ways, flexed and not flexed. They even clear the little tab on the mud flaps with absolutely no rubbing. I think the 4.9" bs actually fits better with the 265/70's than a wheel with 4.5" bs would. Can't say that I like them with the center caps, but capless was what I was wanting anyway. IMO, totally different look without the center caps.
Speedo with stock 265/65/17 Bridgestone Dueler H/T 684 II's (30.6") read 60 mph while GPS showed 59 mph (also 70/69 and 80/79). Odo was spot on with GPS. Speedo with 265/70/17 Duratracs (31.7") reads 59 mph while GPS shows 60 mph (also 69/70 and 79/80). Odo now shows somewhere between 9.6 and 9.7 miles while GPS shows 10.0 miles. So, it looks like my speedo changed roughly 2 mph and odo is off by about 3.5%.
