Wheel and Tire Weights

Yeah looking at the specs vs the non ev versions it’s strange. Obviously they are made for Rivians and similar. What’s odd is their psi is 51 vs regular passenger tire versions are 44. The heat rating for them is better, same tread depth but somehow lighter. Spec wise they appear better than the non EV version but I don’t understand how that is possible unless they are thinner elsewhere or made of different materials.

I have seen alot of factory 34 and 35” tires are specially made to be lightweight and must be giving up something in return (Goodyear territory mt in 315/70r17 is a prime example used in a bunch of oem “35” in applications).

 

I scratch my head at that as well. If memory serves, the Toyota-spec Michelin LTX-AT2 that came on TRD models from 14-21 also had a max inflation pressure of 51 psi bs 44c and we’re lighter than non-Toyota-spec AT2’s.

EV spec, IMO, is mostly just marketing so that when EV owners are looking at tires they feel better about buying them or it’s easier to find the OE size. EV’s are heavier so they legitimately need a stronger tire, but not necessarily an e rated tire.

 

It's supposedly designed for electric trucks. Google the name and you'll find plenty of comments/reviews.
