Tire question

It's that time I need six tires, But I'm not sure which ones to get right now I have Goodyears 255 70 22.5 and I was thinking to go with the Michelin's 255 80 22.5 but the problem is that the goodyears are load range H and the michelins are load range G wich is a step lower on the plyes, the reson I want to go with he 255 80 22.5 it's for the Toller profile to have a softer ride, do you think I will be ok with the load range G. I have a 2006 discovery. Joe

Joe, your manufacturer provides you the information you need. Check the front axle weight rating (GAWR), and rear axle weight rating (GAWR). Do the appropriate math for the duals on the back and the singles on the front. Once you have that figured out, you now have the load ratings needed, per the manufacturer's specs and your tire sizes.

Next one must make sure the dual sizes don't scrub each other. This info is also available from the tire manufacturers.

Another good way to determine new tire sizes is to call the manufacturer of your chassis, with your VIN and s/n from your coach manufacturer.

Michelin is a good choice.

FMCA and Monaco clubs offer discounts for Michelins. Worth checking out.

Do you know the load each tire is carrying now and the required pressure for the load?
Have you looked at the pressure requirements for the new load range G tires for the weight they will carry?
You will probably have to carry more pressure in the new tires for the same load which defeats your reason for changing load ranges.

Hi Joe
I put michelin XZE 255/70R/22.5's "H" rating using the FMCA MAP. Their list price $469 plus $18 FET. I got mounting and balance etc at approx $50. each. Just a thought.

Costco has:
Item # 137063
Michelin XZE
255/70/R22.5 LR H

495.99 Each plus Tax. They will install as long as they can get the Tourque for your Rig. If they install the Charge is $15 per wheel includes Nitrogen

Best to Contact your local Costco to see if they can do it.
