Tires are Goodyear G670 RV, 275/70R/22.5 with a manufacture date of week 33 in 2007 and 23,700 miles on tires. There is some cupping on the inside of the first tread on the passenger side, and my limited experience tells me this may be due to improper camber or balance. Any opinions from the experts on this forum would be welcome. I plan to take the rv to a tire store next week and have it checked. Weight on the tire is 4,619 lbs and pressure is 100 psi.
I have read on this forum that a cupped front tire can be changed with the inside rear tire without any safety issues. Or, would it be better just to replace the tire? All other tires are fine with no cracks or cupping etc. Any comments on doing this would also be appreciated. I know some say to replace all tires at five years.

You will find this is NOT cupping, as cupping occurs from the shoulder into the tread, not just inside the 1st tread. You WILL find this is the dreaded "rivering" that the G670 tire is famous for. There is NO way to stop it, but it can be slowed down by running 10# to 15# more air than the weight chart calls for, up to the limit of the rim.

I agree, .. the GY G670 tire is well known for the rivering condition. It showed up on mine at around 24k miles, so I increased the tire pressure as mentioned. I'm not too concerned as the tires will "age out" before the condition becomes a problem.
Goodyear tires are NOT in my future when it's time for replacements.

Yup, long time known problem and Goodyear doesn't seem to want to fix it. The only way I know to prevent it is to buy something other than GY

Cupping and Rivering are two different things. The best tire wear guide out there is:
http://www.kaltire.com/index.php?page=tire-wear-conditions.
That way you can actually see what your problem is and it tells you the Probable Causes and Corrective Action. And that is about the best expert you will find around here, a tire site! But I must confess that there are a couple guys around here who really know their tires - cause they have been in the business.
Erosion Wear is also called Rivering. You can also see a reference to it in Bridgestone Truck Tire Guide on page 32.

I put Goodyears on 3 of my Mack tractors way back in the early '90s. At about 25K, all 3 sets were "rivering". Goodyear Rep said it was a problem with the truck's steering alignment. Bull Cookies. The steering systems were in perfect condition. I replaced the Goodyears with Michelins & Bridgestones, end of problem. Three of the four Goodyear Wranglers on my '99 Jeep Wrangler had broken belts at 20K, Goodyear would not address the problem. My Son-In-Law had the same problem with Goodyears on his conversion van, no help from Goodyear. Phooey on Goodyear, they can keep their so-called tires.

Billy you should get them Checked. Seems the sour grape group thinks everyone has a rivering issue but you may very well have a cupping issue which is a completely different problem. It could be a shock issue or something else. Have a expert look at them for you and not a diagnosis from a chat board.

Goodyear reps must all go to to the same "denial school". Sounds like you have the famous rivering problem. There is only one cure. Buy something other than GY. Strange how a supposed RV tire turns out to be the worst RV tire ever made. The GY670's should be recalled and replaced at no charge. But with GY's infamous customer service this will never happen.

I have Hancooks on the front and they are rivering.
I run min. tire pressure due to the famed F53 ride.
I would rather ruin the tires then bounce over every road imperfection.
And Age will way out do miles.
