___In terms of wear, the Corolla LE w/ Auto had almost 30,000 on her GY Integrity’s with 35 #’s all around (the Prius II is OEM’ed with those) and was showing edge wear as well as total wear of 5 - 6/32 of 11/32nd’s when new. Within 3 - 5,000 miles of that discovery, I had them up to 50 #’s. Edge wear was stopped dead in its tracks and the family and I drove her for almost another 40,000 miles afterwards. I replaced them just 2 months ago at the 68,000 mile mark w/ 2 - 3/32nd’s left and even tread wear all the way across.
___To sum up the Integrity’s wear both before and after driving them to pressures beyond max sidewall, I had uneven edge wear and had lost ~ 5/32’nds of tread at the ~ 30,000 mile mark while running 35 #’s. Over the next 38,000 miles and running 50 #’s, I lost just 3/32nd’s tread wear, edge wear was halted, even tire wear across the entire face, and of course the much enjoyed increase in FE.
___The Insight’s Bridgestone RE92’s are only down 2-3/32nd’s of 9/32’nds after 36,000 miles from new and they are only a 30,000 - 35,000 mile tire to begin with! I just took the RE92’s back up to 55 #’s last night in fact due to the natural bleed off and temperature drops so make sure you check them often …
___Finally, although only a wish right now, I pushed the Continental’s on the Ranger P/U back up to 50 #’s last night from the ~ 44/44.5 #’s I found them at after almost 3 months of not paying attention. With our fluke 52 - 61 degree temps for my drive home tonight, I dropped under ½ tank (per the Fuel Gauge) at the 368 mile mark. Although it is not entirely linear given the extra ~ 1 - 1.5 gallon available at top off, I might actually hit 40 mpg’s on this tank? That is if the head winds are not to strong in the morning and afternoon temperatures do not sink as fast as forecasted. The only way this type of FE is possible is with the tires inflated to 6 #’s above Max Sidewall and the rest of the techniques and setups we all use. Our temperature fluke sure helped out tonight as well
___Good Luck
