Westlake tires?

My new Grand Design came with these, G rated, and they are marked 110psi cold. How many run them at 110?
  • Why wouldn’t you follow the RV and tire manufacturers’ guidelines?
  • Why not run them at the pressure the sticker on the trailer says to run them?
  • Guess I will. Sticker says 110, just wondering why it left the factory at 90. Thanks.
  • Who knows why the factory does what they do. I would be concerned that the delivery company ran them low and they may be damaged. I would talk this over with the dealer and if you have tire failure in the near future I would demand new tires all around.
  • I would run them at 110. At least with the delivery tow, it would have been close to dry wt, so not quite as bad, as running low pressure with a load. Nice TH, hope you enjoy some fun times with it!

    I run my Westlake G rated tires at 110 psi. They are on my 2018 Grand Design Solitude 379 FLS (14,000 lbs). I stay at 64-65 mph on the interstate. I know I can run faster with the G rated tires but I'm on vacation when travelling with the 5er so I'm in no rush.
