Tires for Big Class C
Hi, Folks, I have a 2011 Itasca Impulse 31N, a 32' class C. This motor home is big and heavy compared to my last one (1999 Coachmen Catalina Sport 220-RK) and is close to the max load range of its...

Hi HikerRob,
Fuel mileage (so far) has improved from a low of 7.13 (225) to 8.7 (235). Best I have done on the new 235's is 10.32. The running average on 2470.1 kilometers (1534.84898 miles) is 8.94. (I converted to US gallons for you)
Improvements are a better ride, quieter inside the RV, more stability on both gravel & pavement, even less wind effect from passing semi trucks (going the opposite direction).
Deficits seem to be a little more control need on steering--but that may just be me.
There do not seem to be increased stopping distances. I'm a slow driver and often coast to a stop when I can do so safely.
Here is a link to the wheels:

I would welcome a 1.25" increase in my road-to-motor home distance, especially at the end of my 11' rear overhang. And you’re right in that the increased tire load rating doesn’t change the chassis load rating. You mention a slight increase in gas mileage. I’m guessing that comes from the larger diameter tires. If so, do you notice lengthened stopping distances?
Thank you all for your interest in my dilemma. I appreciate the feedback.
