Just received some tire quotes we have some uneven tire wear in the front end and the right side drive tires are worn more than the left side which look brand new. The bus pulls a good amount to the right even on flat road with no crown. So we are looking at getting an alignment putting two new 365s on the front changing out the 2 old drive 315s and putting the best two of the four 365s on the tag.
New tread depth on XZA 365/70R22.5 is 19/32
New tread depth on XZA1 315/80R22.5 is 18/32
All tread measurements are not taken to wear bars and in the center of tires. Take 2/32 off each tire for wear bars.
Steer – Driver (12/32) Pass 11/32)
Drive – Driver (Out 16/32)(In 17/32) Pass (In 7/32)(Out 8/32)
Tag – Driver (13/32) Pass (11/32)
Could the slightly larger drive tires 17/32 vs. 7/32 contribute to the pull to the right? Would you mix the new drive tires with the old by putting the 2 new on the outsides, or just put the new set on the passenger side duels because it seem like that side wares faster due to road crown?

This bus only has 30,000 miles on it seems like a lot a tire wear from reading other post here where age comes into play long before tire wear.
