Tires

[Pyromedic]

I was walking around my new Windjammer 3006wk and was looking at the tires.
Some have said to go with E rated tires. These are D rated at max load of 2540lbs. X4 that's over 10,000lbs of rated capacity. I think I'll stay with these for now. I will consider going to the E rated for my next set in the future. My old camper was a Flagstaff 831bunkhouse and that had C rated at 1820lbs Max. That camper was 6500lbs dry and I know now those tires were way over their limit. Keep in mind of your camper weight and added weight of gear (gas, battery, water, etc.) and what your tires are rated for. Happy Camping 🙂

couple of things besides weight to consider when thinking about the rating of your tires. I have "C" now and will be changing to "E". The speed you drive, ST tires have a 65 mph limit (I don't exceed this). Where you camp, I need the E rated tires (for the ply rating) because of backroad Idaho camping. It is very easy to put a rock thru the tread or sidewall.

Your Flagstaff may not have been over. Your tongue weight is carried by the TV so you would subtract TW from actual gross weight of RV. It might have been right at the border as it was with mine. I jumped up to a D rated tire from C rated. Not so much for the increase in capacity, which by the way, you are still limited by axle weight, but more for handling. Stiffer side walls helped a lot with pitch and roll. I seemed to do some bobbing and weaving on the old tires. Not to confused with sway, just a lot of rocking back and forth. My RV tows better have higher rated tires on it.

I don't run with the crowd that immediately buys new tires before they get their new rig home, but I strongly recommend thorough tire examination every time you are ready to hit the road, looking for proper psi, tread separation, bubbles and abnormal tread wear. Also buy a cheap infrared thermometer and check each tire at every stop for large temperature variations. If you get a couple of years out of the existing tires then might be a good time to do the upgrade.

The OPs tires pictured in his post are clearly marked with a speed letter "L" for 75 MPH. (113L)

The TRA has increased the recommended speed restriction on ST tires to 81 MPH. All new ST tires from "off shore" manufacturers will now have speed letters. Some have even lettered them for 87 MPH.

My C rated tires are also Speed Rated L - 75mph:

[Pyromedic]

Thanks for the tips guys. I didn't realize the speed rating of L' on the tire. How many of you are towing at 75mph. I've always tried to stay around 65mph.

I think my Kumho 857 are rated for 75. I have towed at 75 mph . But the Jeep gets around 10.5 at 75 . Slow down to 63 or so and mpg's are 12.5 to 14 depending on wind and hills. I'm not really in a big hurry any more. We save more time if we don't go inside anywhere. Get diesel and us the trailer .

Pyromedic, I checked 2015 windjammer specs on FR add and they list it at about 7500 uvw plus 1500 cargo in round numbers. It looks like tongue weight is included in uvw in literature so tire capacity would not appear to be limiting factor. Nice looking unit.
The larger tank capacitys are great but limit ccc. I rarely would travel with grey and black tanks full except to dump station and like the extra grey tank size
I have D tires and the wheels appear to be ok for E so when I replace them I will also look to E and see if height is not a factor I'll use E then. I don't know if tire dealer will agree to replace original size but I'll cross that bridge then.
Mostly rural with 55 limits here.

Just 'cause I can doesn't mean I do. I do 60-62mph.

The 857s are rated to 99 mph

[HONDAMAN174]

I had the 857's on my Hw pop up. Would have been interesting to pull that thing @ 99 mph. Of course, we have all seen someone at 80+ and just waited to see some carnage.

I don't think I'll be doing anything over 70 but, it's good to know I have a decent set of tires.

Thanks for the compliment on our choice of new windjammer.

Be safe out there....

As Airdale has pointed out, there has been a lot of recent changes in the ST tire process, and the 65 mph blanket statement is really no longer valid. There are just so many ST tires now that will not be covered by that speed factor.

[BDavis]

I installed the E rated Cooper trailer tires on the same trailer and noticed a huge improvement in handling/sway and they are also speed rated a little higher as well. Just a better margin of comfort.

[hdmtnrider]

BDavis, what Coopr tires are you using and where did you buy them?

[missing_link]

My 2014 3006wk came with C tires and I will be upgrading to D. If the newer units come with D already then there should be no need to upgrade

Not sure where you got your information Seadog but there isn't a tire that is meant for the highway that is rated for less that 75mph. S rated is 112mph. You may not want to tow anything faster than you can do so and handle/react in a safe manner but it is not the tires that are holding you back unless you are exceeding the weight index rating they were made for.

L 75 mph 120 km/h Off-Road & Light Truck Tires
M 81 mph 130 km/h Temporary Spare Tires
N 87 mph 140km/h
P 93 mph 150 km/h
Q 99 mph 160 km/h Studless & Studdable Winter Tires
R 106 mph 170 km/h H.D. Light Truck Tires
S 112 mph 180 km/h Family Sedans & Vans
T 118 mph 190 km/h Family Sedans & Vans
U 124 mph 200 km/h
H 130 mph 210 km/h Sport Sedans & Coupes
V 149 mph 240 km/h Sport Sedans, Coupes & Sports Cars

JMO, but anyone towing 70+ is a disaster waiting to happen. Don't care if you are towing a rv 5er with a Peterbilt, it's going to be gruesome if the trailer has a flat.
