Yeah, Thats the right size! 325/75/R20 Pirelli Scorpions! I asuming thats the reason why my MPG's are so LOW! Trying to get up to 15-18 because gas here is over $5 a gallon.

Yeah, I am sure that it has been calibrated because I also run the calculations that i travel by had! it you go to fully.com and search for BIG RED you'll see my comments on the travels I do. But thank you for the comment!

All I need now is to find like Widespread Hummer said look for the Rims for the H3 Chrome on Craigslist/eBay which I hope I can as soon as possible!

Thank you guys for the comments!

When you run the cleaner through, may I suggest the Sea Foam motor treatment first, then go a tank and, then try the injector/fuel cleaner.
I was given this advice from the guys here on this forum and it sure worked for us!!
My thanks to those guys

Happy driving!!

We are moving from a Nissan Murano to a lightly used 2006 H3. I averaged like 15 mpg in the Murano so it sounds like this is in the same ballpark. If I could get better that'd be a miracle. I think I'll be trying to pull the weight down a bit and get some more road type tires too.

I am now running cleaner every 3 tanks of fuel, we only have 33k on the rig so its just broken in.

Good luck with the tire issue!!!
