- RTFMOKExplorerI did confirm that the dealer my lady got the TT from did put the tires on in 2014 when she bought it. She did not like how the existing tires looked.
Dirty birds installed "new" 4-year-old tires! At least they gave her a set of 5. - myredracerExplorer II8 years? :E Much too old for ST tires. I'm replacing our Marathons after the end of this season at 5 years old and will go with the new Endurance tires. They look like they could go another 20+ years... :(
How long they will last will depend partly on how they were treated. Heat kills ST type tires and will accelerate aging and risk of a blowout - from towing over speed rating, towing under-inflated and/or towing overloaded. ST tires can still *look* new but be due for replacement. Going up one load range on replacement tires can help a lot because it gives you more reserve load capacity (reduces internal heat). The last thing you want on a towable RV is a blowout due to the expensive damage it causes so don't take chances. 5 years is a good max and some go even less but again, will depend on how you treat your tires.
Roger Marble has some great info. on tire age on his RVtiresafety.net blog here. - mkirschNomad IIMy enclosed utility trailer has "Triangle" brand tires on it. 14 years old. Tires still look brand new. No signs of cracking, rot, or anything.
Would I recommend 14 years for a travel trailer? No.
I'm just saying the brand has impressed me so far. - gmw_photosExplorerMy next set of tires for my travel trailer are going to be Hankook RA18 light truck tires. IMO, this would be a good replacement option for what the OP has.
It has a load rating 104 which if I remember right is 1984 lbs at 65 psi for this tire. That would be approx 25% reserve for a 5K lb trailer:
https://www.amazon.com/Hankook-Vantra-RA18-195R14-106R/dp/B01G2C14U4 - Grit_dogNavigatorYes a 30% cushion for load rating is fine, but like other things, depending on type of use, having more factor of safety is not a bad thing.
It’s risk vs reward. And for trailer tires that are unusually prone to higher than normal failure rates than car tires, another $10 a tire for an overkill load rating is not a bad thing.
I’m looking at my, now going on 10 year old boat trailer tires that haven’t had more than local trips on them for the last 7 years now, garaged all year, look like new and struggling a bit with replacing them for longer trips planned this summer. But they’re getting replaced. Have too many past blow outs and busted up fenders to not drop the $400 on new tires. - RTFMOKExplorerThanks for the feedback. Also requests for more info from me.
I do see some minimal sidewall cracking, no cracks between the treads. The tires were supposedly new when installed in 2014 by the dealer my lady bought the TT from, but the date codes show 2010. The 4 road tires all evenly lost about 5 pounds sitting since last summer when last aired up. Spare was down 15 pounds, never been checked, at least in the last two years.
The current tires are Tow Masters, load range C, size ST205/75R14. Rated 1,760 pounds each X 4 is 7,040 pounds. That is a cushion of about 30% over the TT max weight.
I have not found the actual axle ratings yet, but the TT is a 2-axle rated for 5,000 pounds max weight.
Does replacement with same load range sound reasonable? I'm still hunting down the trailer specification to see if it calls out different size or load range. - dodge_guyExplorer II5 years is the average. I just ordered my 3rd set of Carlisle tires. The first 2 were Carlisle RH. This set is the HD`s. I haven`t had 1 failure. Each set had approx. 8k miles and were 5 years old. towed in extreme conditions, 90+ degrees, 70-75 mph. The first set I found a shifted belt. So I guess there was a failure, but it didn't affect me. the current set I don't see anything.
- valhalla360Navigator8yrs is pushing it.
5-7 yrs is the commonly accepted lifespan. - I only recommend 80+ mph speed rated ST tires including Goodyear Endurance and Carlisle Radial Trail HD. Currently I run Goodyear Endurance. MAXXIS was coming apart just shy of four years.
- 67HotRodExplorerMaxxis, and I change tires at the 5 year mark. I travel allot of back roads that usually don't have a friendly place to stop.
