BFG all terrain 275 70 17 psi?

[jameygraham]

I have a 2016 Trail with new (less than 2000k miles) BFG KO2 275/70R17's and when they are at 40psi they feel too tight and bumpy on the street/hard pavement. 34-38psi feels instantly better. Anyone else feel the same? Does anyone think running these tires at 34-38psi is bad for the tire especially on long highway roadtrips?

Quick update on PSI from my side. My dealer informed me yesterday that regardless of the tire, I should always follow what is specified on the inner driver side door because
a) it takes into consideration the weight of the vehicle and
b) that number is designed to improve the tread life of the tire

The number for my '16 Trail is 32 PSI which seems low but he explained that using this PSI provides better surface contact between tire and the road and reduces the chances of irregular tire wear. Given this information –*and assuming it is valid –*I'm surprised when I see such high PSI numbers ... Thoughts?

If you were running comparable p-rated tires, of the stock size, then yes, the dealer would be correct. That is why that sticker lists the tire size and rating.

You are running a different category of tire and maybe size, so they are not directly applicable.

That's funny. My dealer told me to run the standard 20 inch P series tire at 40psi instead of 32psi. I did and I like the ride a LOT better, got better gas mileage, and thought it handled a bit better. Hate the tire though so about to ditch them as as soon as my SCS wheels get here.

I have those exact tires. I contacted Michelin about my previous set of LT tires (M/S2's) and was told to put 50 psi in them. I have found that, depending on cargo weigh, 45-50 psi is ideal for the KO2's for on-road driving. I drop that to 15-20 psi for the off-road adventures.

I ran mine at 35psi initially and it felt very "floaty". I bumped it up to 42-45 ish psi and it feels so much better and the gas mileage has improved since.
