Hey All!

I've had some tire issues in the past so ready to try something different. I have been running toyo's forever out of convenience.

I was planning on going with the Michelin LTX A/T2 tires but I see these Michelin Agilis Cross Climate tires. They are about the same price. So wondering if they are better.

Also I see the XPS Rib which is a fair bit more but if it means no tire issues, I'm in!

Or if there are some higher weight capacity tires I'm missing please fill me in.

What do you all think?

Thanks!

Generally all tires of same size and load range have the same weight rating, so no chance of more capacity without upsizing tires.
But not being specific about the issues you’ve had, dunno if you’re needing more weight capacity or not.
However, quality wise, I don’t believe you can do any better than Toyo, so your issues likely don’t reside with the brand.

How much is heavy ?

An E rated tire is the common tire for class C’s. I have been running many tires in fleet trucks , IMO, i have not found much difference between good quality tire brands.

Toyo’s are very good tires. A common tire used today on class C’s is the Hankook Dynapro HT RH12 which i have and are fine. Many owners run them with no issues.

If you decide to choose a winter tire , they offer better traction in snow but mostly dry pavement running might cause premature wear. Just something to look into .

I would not base my purchase on which tire manufacturer spends the most on advertising .

I believe that the Agilis Cross Climate replaced the LTX A/T2. It's basically the same tire, just a different name.

If you want significantly more weight capacity, you will need to go with a higher Load Range tire. If you have Load Range D tires go with Load Range E; if you have Load Range E tires, go with Load Range G tires.

FWIW I ran a set of 4 LT245 70R16 LTX A/T2 tires on my Roadtrek to about 70,000 miles until they finally wore out (started seeing some tread separation). I still had enough tread depth on them to prorate a new set of LTX MS2s to 50% price. They were great tires and the aggressive tread pattern made them good in sand, snow, mud. I believe the CrossClimates are similar.

I like the all-steel cased commercial grade tires like the Michelin Rib or in our case we run a set of Bridgestone Duravis R238s. All LT225/75R-16 tires have to pass the same testing in the NHTSA FMVSS 139 test. But I believe you get more design margin in a heavier all-steel cased commercial tire. The all-steel cased tires weigh 9-10 lbs more per tire than the non-steel cased tires and I like riding on 25% more tire.

Our previous set we ran for 8 years, a set of Bridgestone Duravis M895s. Great tires, never let us down but no longer offered by Bridgestone. M+S rated unlike our current All-Season tires. Similar to the no longer available Goodyear G947 RSS Armor MAX. I don’t know of any good all-steel cased commercial M+S tires. Possibly the Michelin XPS Traction which had a more aggressive tread.

Going to a 'G' tire in 16" will be a narrow field of availability. If you could find a size that fits, it would ride harder and the OEM wheels at 110lbs vs 80 lbs. PSI, might not support a 'G' tire.
I would think OEM RV tire manufacturer picks would compliment the rv's GVWR.
You should not need more than an E tire on any class C within specs.

Letter and ply ratings are not the most accurate weight rating. It should be embossed on the side wall.

Yes, hard to believe you would need more than Es. I have a C that is over-weight in the rear without anything added to go camping. Seems to have been built that way when they added the RV part to the "incomplete truck" they got from Ford to make an RV out of.

On the scales I got the true back weight when loaded as for camping and looked up the proper PSI for the four LT Es on the rear, and it is 65 lbs vs the 58 lbs the door label says the rears should be.

65 is no where near the 80 the Es can do, so how over-weight can you possibly be to need more than 80???? No way!

What are your scale weights?????

On my 30' Class C RVs, I have made the choice to go away from the E rated tires and instead go with Commercial tires with a 121/120 weight rating. I buy my tires from Big-O tires and they don't seem to be any more expensive (~$20 more per tire).

With E rated tires (which is what the manufacturer recommends), if the rear axle is at max load there is very little extra weight margin and my opinion is that the tires are being stressed (...especially if they ever end up not being properly inflated). Tires at their max load MUST have a higher chance of a blowout, right? With Commercial 121/120 load rated tires, they give you an extra ~2000lbs of carrying capacity (compared to E rated tires) on your rear axle and I sleep better at night knowing this.

I just bought 7 new Commercial rated tires last week for one of my 30' RVs. The tires were $135 each.

Personally, I haven't noticed any difference in terms of handling or noise.
