My 275/70-16 OEM LTX M/S are 666 rev/mile. At 672 rev/mile for 275/60-18, the difference is less than 1% between the two. If SWUtah does not mind the lower load rating on the Pilots, then the difference of 1% is negligible.
Thanks, I went back and compared the numbers of the 275/65/18 REVO's - 649 rev's per mile and the 275/60/18 Pilot LTX - 673 rev's per mile. Equals about 3 1/2% difference and would extend my CPO warranty by about 2000 milesI got my info from the Michelin site specific for the specified tires rather than a average calc for the size in general.
While the tire calculators give a good ballpark number for reference, they do not get to the specifics of the actual tire. Tire Rack has links to the mfg specs on the tires or you can access the mfg site directly to get the specific info on rev/mile along with other factors such as tread depth, rim size, actual width and height, etc.
The Pilot LTX M/S appear to be an 18 in H rated LTX M/S.
I have the LTX M/S 275/70-16 114H with 2365 lb at 44 psi and 666 rev/mile. This is the OEM tire for the LX and custom made for Lexus. It has a UTQG of 440 A A, so it is more performance oriented than the S rated tire.
The Pilot you mentioned is also OEM for Lexus in the 18 in size: Pilot LTX M/S 275/60-18 111H with 2185 lb at 35 psi and 673 rev/mile. Its UTQG is 400 A A.
For some strange reason my LX came with the S rated LTX from the dealer though the sticker says H rated. It must have changed when the wheels got chrome plated.
The S rated LTX seems to have less rolling resistance (slightly better MPG), but the H rated handles and rides better. If I was choosing tires again, I would still pick a 16" H rated LTX for general use. If I did a little more off roading I would look at the BFG TAKO, or the LTX A/T in 265/75-16.
It looks like the Alenza is essentially the same in revs/mile plus you get the better load rating. I doubt the Pilot 18" is a problem, but the Alenza looks like a good fit.
With swings in the industry of more than 10 revs/mile within the same tire size category, I can't imagine the dealer having a problem with 5 revs. I have not heard of a dealer having a problem with the tires unless they were major changes - e.g. lifted truck with monster tires. They may have questions about the tires, but any adverse warranty issues would be limited to those affected by the tires.
no, but if you need another set i have 4 in my garage with 3k miles on them and will sale them for cheep. The cost about $1000 new.
Anyone know how these are in heavy snow on a 2003+ LX/LC? Not taking my rig off road, only to the mall, so I want quiet smooth and good traction in heavy snow. Anyone experience with these 18" Pilot LTX"s would be great.
Thanks
I've currently got the Mich LTX MS 275/60/18 on my 04 LC. They just safely took me over three 10k passes in Colorado during a big snowstorm. I have nothing to compare to, but they and the LC where very sure footed. It's a daily driver.
My next set will be the MS 2, but they no longer make them in stock size, I'll have to go up.
Be careful about warranty companies and different size tires, they love to deny a repair for any reason whatsoever!
