I went to NTB a few days back to replace my P Rated Cooper RTX (265/75R16) - it's their version of the AT2. Turns out they installed the LT version of the tire by mistake (among other screw ups that I won't get into). They were closing but the guy offered to swap them for the P rated if I came back. So I'm trying to figure out if I should.
I really don't offroad all that much and I never tow. I definitely don't *need* LT tires. That said, they do look kinda cool, and the improved durability is a plus. I thought the increased tire weight (50 lbs vs 40 lbs) would have a big effect on efficiency but I'm not seeing all that much. It's a bit hard to say, because I haven't had enough time to do a full tank's worth of driving to compare, but the Ultra-gauge is showing about ~15 mpg in the city. What surprised me is that the highway mpg was actually higher than my usual - 23.5 vs about 21.5 on P rated RTX. Maybe from the higher PSI and stiffness? The 4Runner is basically stock, FWIW.
Also surprising, I'm not really detecting a rougher ride that everyone talks about. I'm running the OME 906 so it's kinda rough already.
I'm wondering if all the stuff online about bad mileage and stiff ride is because most people go from a P-rated highway tire to a E-rated AT tire. Who would go from P to E with the exact same model and size (except me)?
Should I go back to the P, since the E is definitely overkill? Or keep the E since I got them at good price and I'm not seeing any negatives with the ride or much of a dent with mpg, at least on the highway? Assuming that the LT reduce efficiency by 1 mph, that's about $500 over the life of the tire, so it's not nothing.
