Tire and wheel update after 8500 miles

[sully06]

Yeah and I really like the tread pattern

58psi, is that just a little over the max pressure? Dangerous?

Higher or lower UTQG does not necessarily correlate into rolling resistance, especially across different brands. I have seen it work both ways on different occasions. Way too many variables between tread patterns, tread compounds, psi ranges, actual diameters, etcetera to directly correlate.

Also to clarify the three UTQG ratings are for treadwear, traction, and temperature. The speed rating is part of the service description, which consists of a load index and a speed rating.

For example, compare the following:
Michelin LTX M/S2
Size: P265/75R16
Serv. Desc: 114T
UTQG: 720 A A

Dick Cepek Trail Country
Size: 265/75R16
Serv. Desc: 116T
UTQG: 500 A B

Yes, a bit of an extreme example, but it should be clear from looking at the tread patterns which tire has lower RR, and note that the UTQG doesn’t correlate.

Well the max is 51 I usually keep them at 55 but put a few psi more for the trip. I had 55 in the Goodyears which had a max of 44 for over a year. I knew the risks of having a blowout were higher but was ok with that.
