Today I just installed 4 new Michelin tires on my Newmar Allstar!

Line Energy Z in a 275/80/22.5 for the fronts (in place of the 305/70/22.5 that was on there)

I changed this due to overall availability and lower weight and rolling resistance... the 305's are hard to find and the 275's are readily available... with the load range H it has enough weight capacity for me.

On the rear I got 445/50/22.5 Michelin Multi Energy T tires with 14" wide Alcoa lightweight rims. The overall weight savings on just the rear axle is around 350lbs! That is a TON when you think about it being unsprung weight.

So I have not yet driven it, but I am excited to early next week and report back on the performance.

Per Michelin's calculations I should see about a 7% increase in fuel economy due to these changes. I will take notes and report back on that too.

So for those worried about getting a flat and tire availability - I chose tires that the trucking companies use daily and are generally in stock across the country. A good friend has the same coach as me and it took a long time to get a 305/70 XRV.

Cheers!
