First trip on the full complement of G670s (295/80s)
Ride is quiet and greatly improved (although I expect most new tires properly inflated would be an improvement over aged toyos).
Speedo is almost dead-on (gps check).
It was ~1.5% fast.
And, no more annoying door squeaks.

Replaced toyo's with goodyear G670
Just had my original Toyo's replaced with Goodyear G670 295R80 22.5. Went to Wingfoot in Phoenix. Out the Door for $3300 and the $80 per tire rebate lasts till the end of Sept. Brings the cost down to a little more than $2800. I was told to run 105 psi all the way around. Does that sound about right?

105 in front and 95 in the rear is what I have in my new G670's. You don't need 105 in the rear. In fact, you could go with 100 in the front and 90 in the rear.

Just curious Jerry,
Did you go with 295/80s?
Reason I ask is, as I read the load table:
http://www.goodyear.com/rv/pdf/rv_inflation.pdf
There's a significant "step-up" in load capacity with this size over smaller sizes, arguably closer to some stock Alpine tires.
It looks like a 295/80 matches my axle ratings 13K (front) / 20K (rear) at
~100lbs front and ~85lbs rear.
Coaches that have not maxed out axle capacity could presumably run less, notwithstanding advice to run a little excess margin.
Some of the shorter coaches with a lot of CCC that weigh in much lower than max axle capacity, could go even lower, even with a margin.

Jim/Mary
I went with the 295/80s for the high load rating you mentioned. Seems like a great fit for our coaches. I have no interest in having a weight related blowout that some of the original Toyos were having.

Good luck on the tires! We ordered our Challenger 355 in Dec 2006 and received it in Jan 07. Ours came with Goodyear G670's date coded 2806. We had no problem till this summer. Had a inner dual sidewall blowout at 17,800 miles. Goodyear has a 6 year warranty against defects, so they paid a good portion of the price for a new tire. Defective tire?, it happens. Another 130 miles and we had another tire blowout, this time a steering wheel. Blowout was in the same spot on the sidewall. We had that one replaced on the road, thanks to good sam's road side service. Made it to the campgrounds and I took time to inspect the remaining 4 tires. Found the sidewall bubbling on another one. I've worked with Goodyear on the remaining tires, they claim there is no issue with that series of tires, but they decided to replace all my remaining tires with new ones at no charge. So those of you with Goodyear G670's might want to look at your tires.

You realize this thread was from a year ago, don't you?
We went to Michelins.

Swanset, I was aware this was an old thread but felt clarification was needed. I will replace my fronts with Michelins some time this year. My G670 295/80R 22.5 H rated tires will be 5 years old in August 2011.
