I have a 2012 Dutchmen Infinity fifth wheel and want to upgrade the tires from E rated (80psi) to G rated tires (110psi). I checked the rims and there is no place where it is marked with the max pressure for the rims. I had two blow outs within the last year, one did minor damage and the other did three thousand dollars damage. I did a little research and I think I'm going to upgrade to the goodyear G614 tires. I believe the rims are aluminum and was wondering if I need to get new rims also.

If in doubt, I would change them.
Could you check with the Dutchmen for info on the rims?

If you go for the new rims also ... go all the way and upgrade to "H" tires (Goodyear G114 or similar) as well... highly recommended by many seasoned RVers on here. Use the search tab at the top and type 'G114' for more info.

Highly recommend you don’t go to “G” tires and follow Brian’s comments and go to G114 “H” tires.As you have to change the wheels / rims anyway go to a tire that is known not to blow out and “G” tires blow out – just not as often as “E” tires.
G114 “H” tires are expensive, but they will last twice or more miles than the “G” tires and won’t blow out due to side wall failure.The “H” tires are a commercial tire. Not an “RV” tire and are made accordingly.
Many, including Howard and Linda, have used this company as a vendor.The tires come mounted, balance and ready to install.There are numerous treads on the site concerning this recommendation. We have some 85,000 miles on "H" tires without issues and that includes some pretty bad roads in Canada.
Call (419) 272-2277 – Ask for Scott – tell them what you have and what you want and they can help.
BTW, welcome to the forum.Hang around. There are a lot of knowledgeable people to help with any questions.

Thanks everyone for all the info. I talked to Dutchmen today (which now is Keystone Dutchmen) and they didn't give any good information. They told me to weigh the trailer and E rated tires are the right tires, I just said thank you and goodbye. I'm going to take your advice Bill and Brian and go with the H rated tires with new rims.

There should be a stamp on the inside of the rims with the max load numbers. Go with the G114's I just switched last week and what a difference, Just knowing I'm riding on a MUCH better tire. No regrets whatsoever on the $$$$. Safe travels.

To add my 2 cents to this, I totally agree with going with the "H" tires and rims. I also used trailer tires and wheels after 3 blowouts in 5 weeks with "E" tires. We have a 16K rig. You will feel so much better after you bite the bullet and do this.

HOLD THE BUS!!!
You are wasting your money with the "H" tires and wheels, I will tell you why.
First you are at the limits of your "E" tires because that's how RV companies roll. They only put enough capacity to get you down the road. You would probably be fine with Bridgestone or Michelin "E" tires but I like to have a little reserve.
So I had a 32' Avion Platinum and sure enough it had US Made GY "E" tires and held up fine but I was at the upper end of capacity for the tires and they were 5 years old. So I installed GY "G" tires. I called GY Tech Support and talked to them about inflation. They said to go by the RV MFG label wit stock tires. Then she said if upping the load rating that I should weigh my RV fully loaded and then use the load/inflation chart for the "G" tires. Then she said to add to add 5psi to what the chart said.
So I weighed the RV and it said I should be running 80psi. So I ran 85 and did so for 5 years. The tires always ran cool and they had perfectly even tread wear.
The tech said it would be a mistake to run 110 PSI because the contact patch would be decreased and would have less traction and would increase stopping distance. Also the ride for your RV would be very harsh.
I went from GY "G" to GY "H" and 17.5's on my Mobile suites and ran 107 psi for 30K and had very even tread wear. My new 16 MS has GY "H" tires and I will NOT be running 125PSI I will be running what the chart says plus 5PSI.
So yes up size your tires but don't overkill it! I will wager you will need 85psi like I did and yes your rims will be just fine!

herme50,
Do you know what weights each individual wheel is carrying? You may be overloaded on one or two tires, thus causing the blowouts. While we are within our weight limits, we were heavier on our refrigerator tire when weighed by Howard and Linda, so we load the fiver accordingly.

WOW!!!!! So Much info, I got a lot of thinking to do. I did check my rims and the spare have a load rating of 3750lbs and the main rims have a load rating of 3960lbs (couldn't find any pressure stamped on the rims). If I decide to go with the G tires, will these rims be okay? Again thanks all for the info.

Again, before I would do anything, I would have the rig weighed in your loaded mode. How can you make a decision without having all the information you need? You might be carrying too much weight for your axles, let alone your tires. Have each individual wheel weighed.

Go with the G tires and don't look back!
Yes weigh your tires individually. Use the weight/inflation chart add 5psi to the pressure recommended for the heaviest tires weight. You will most likely be airing there tires to 85PSI. Been there and done all that.
