Trailer Tires... again

Attention: TDR Forum Junkies
To the point: Click this link and check out the Front Page News story(ies) where we are tracking the introduction of the 2025 Ram HD trucks.

Thanks, TDR Staff

How much weight is in my truck? Take a guess! (-:

102" wide 5er, factory tow mirrors...

I've been monitoring/paying attention to JCasper's thread.



I have 225/75-15 ST E Carlisles on the 5er. You guys have me all freaked out. :eek:



I definately can't fit the Michelin XPS Rib 235/85-16 LT tires on the trailer. They are 31. 7" dia vs. 28. 3" on my current setup.



However, I can fit the Michelin XPS Rib 225/75-16 LT tires on the trailer. They are 29. 3" dia. They are rated for 2640lbs vs my current 2830lbs on the E rated ST tires.



Trailer axles weighed in at 7800lbs fully loaded.



Should I get the 225/75-16 LT Michelin XPS Ribs?? Even though they aren't the 235/85-16's that everyone recommends??



Now I just have to see if Americas Tire will allow me to trade up without soaking me too badly. (new wheels and tires)



The Maxxis 225/75-15 ST E tires are available at Americas Tire and will only cost me approx $80 to upgrade/trade. I know these are better than the Carlisles, but should just bite the bullet and get the Michelins??



Thanks,

An ST tire are only good for 3 years from the date of manufacture regardless of thread depth and your limited to 65 mph. Put your 5er on a scale, ready for travel, and determine the weight of each axle and the pin weight. Is the Michelin XPS Rib 225/75 16 LT a Load Range "E"? Check with a Discount Tire store. I know of one in Portland and one in Bend, OR. Maybe one in Medford.

I previously owned a 31-ft '97 Hitchhiker II 5th wheel with two slide outs that was equipped from the factory with Goodyear Wrangler HT 225/75R16LRE tires. After many problems with the Goodyear tires, I replaced them with Michelin XPS Radial 225/75R16LRE tires. I ran these tires for tens of thousands of trouble free miles. The Michelin XPS Radial 225 tires should give just as good service as the 235s as long as you keep them properly inflated and don't overload them.

Been watching these threads also, and I have been wondering how much tight turning is done when maneuvering. In other words, how much side wall squirming is done and how is the trailer left parked. Are tires still in the squirmed position? Real tight turns will pull the cords/belts in the tire. You see the tight turn adds for the slider hitches, 90* truck/trailer. short wheel base trucks. Not good for the tires. Just wondering where the failures might be coming from.



I did find a DOT listing on where tires are made, but can't get the link to work to transfere here.

If you go to gglotus.org and follow the links you might find it. do a search on the left hand side of this page, "DOT information", the google will take you to the information page "tire information" and then arrow down for the list. Thanks to the GGLC good luck

ST tires have always been problematic even in the bias ply age especially for our hevier trailers (not just RVs). Looking at Goodyears Marathon ST web says ST tires have a narrow tread design. That narrow tred design leaves the tires sidewall basketball shaped. makes for a softer ride than a LT but at a big cost. Too much tire flex which creates heat. A good trailer tire has a flater sidewall profile. A LT 235/85 or a 215/85 fits in that profile great. next time you come up behind a semi truck trailer look at the flat sidewall profile. There is no bulge like a basketball. check out a same size/load range ST vs LT. The LT will be heavier by 8-9 lbs. Like the Marathons web say they are ecnomical which = cheap.

I use Michellin XPS ribs on the front of my '99 ctd because it chewed up everything else in 20k miles... I have 20k on these and I cant even tell they arent new, they are 215/85/16s. All the other tires I had on the front looked like they were ready to blow (all bulged out) the XPS tires dont hardly dimple... paid $$$ for them, but would do it again, they are useless on snow/ice though... so if you drag your 5er through the winter would maybe look into the traction version. I am thinking of upgrading the tires on the truck to 235s and sticking the 215s on my flatbed since it has the really strong sidewalls.

Lost two sets of tires on my boat and 5ver in two years running Carlisles and will never buy that brand again :mad:
