Is it the xl?

The "P" before the tire size is what I was referring to. Looks like yours calls for P-metrics, not LTs.

Two questions. First, are your tires P or LT? Second, which of those does your door sticker call for?

My Suburban calls for load range C or better LT tires, but I ran P-metrics on it for a while based on the advice of a then trusted tire shop employee (who I no longer trust, long story). They always had that little bulge at the bottom you described. Putting LT rated tires back on it (BFG KO2s, load range E) was one of the best things I've ever done. It drives 100% better and looks proper again.

I'll take a picture of the door jamb sticker for you and check on the load range for my ko2s. Not sure off the top of my head.

Oh I was just asking SUBURBAN5 since he mentioned the bulge in his tires, I'm sure you're good.

Pretty sure all the KO2s are LT, load range E. They're awesome tires, I love them on my 'burb.

No I meant in the pic. Lol. They look solid. I feel like my tires always bulge at the bottom no matter how much psi i put lol. Normally i do 32 in front and 40 on rear

The ko2s on my pickup do have that same sort of bulge I think your talking about where the rubber meets the road... Not sure why. Adding more air doesn't fix it but it hasn't really ever bothered me.

I figured it was just the way it's made lol. Just wondered why some trucks look straight like my company silverado lol. I know theres commercial tires but always had me curious

Oh. I see it now

Means they're rated to 112MPH. It goes up as the letter grade advances. There's a chart for speed ratings about 2/3 of the way down this page.
