Changing from 295-80-22.5 to 315 Michelin Tires

With the FMCA Michelin tire program the 315-80-22.5 is over 50$ less then the 295-80-22.5 any wanted to check if anybody has made the change when getting new tires. Could save over 400$ and run lower tire pressur at the same weight.

Hows the clearance between the duals? That's the main problem with going to oversize tires, the next is clearance when turning the front tires sharply.
I went from 275/70's to 305/70's on the front of our DSDP. Also went to wider Alcoa wheels at the same time. The 305's were the only ones that gave me clearance but even so I have to be sure the front wheels are straight before I dump the air.

As noted above, dual spacing and turning clearance are the potential problems.

315's on the front...12R's rears, Firestones less $$, easy to find on the road if necessary. MUCH better ride than the GY670's. Check clearances. 9" recommended 8.25's are ok with a slight weight carrying capacity, but still better than the 295's. You will be happy

Ivylog is running 315's and 11R's same happy results...and he was first.
