Tires

My wife and I are buying a new Redwood. It comes with Goodyear E rated tires. G rated tires are optional. Is it necessary to upgrade to G?

If the E tires weren't adequate, why would they be standard?

Been there_done that. "E" rated ST tires are loaded to very near their maximum weight rating on most OEM trailers. Load range "G" tires I run now are loaded to approximately 3/4capacity. I have not had one tire issue since upgrading to load range "G" tires.

There are many tire threads on irv2.com; use the search feature to find them. Remember_ you must also have rims to match the maximum load capacity of the tires. My aluminum rims have a 110psi capacity and I run my LR "G" tires at 95psi. to correspond with the mfgrs inflation chart.

ST, load range "E" tires normally are required to run stated sidewall maximum pressure according to their warranty, regardless of actual weight on them.

No, ST, load range "E" tires are not unsafe, IF you replace them every 3rd year, run them at stated sidewall cold air pressure rating, AND stay at/below 65 mph maximum speed rating.

After looking at the specs for the current Redwood models I’d venture a guess that the certified axles on your trailer are 6750# ea. That would mean the LRE Goodyear’s would be very close to maximum capacity when your trailer is loaded for the road. If that assessment is true, the upgrade to the Goodyear LRG is an outstanding option.

well maybe this will help. I had a goodyear marathon load range E - It blew out with less than 5k on it. brand new tire. I not only would go with the G I would put pressure sensors on the wheels as well.

Personally.. I'd upgrade.

I can not say the heavier tires are necessary (however the other respondent makes a very good case) I can say every trailer I ever had popped tires like kids at a party with balloons,, Upgrading fixed it every time.

Yes go with the G rated tires. The E rated tires are the cheap low bid tires.

Go with the G rated tires and make sure that you will also get 110# rated rims.
I bet you would be getting 7K axles with less capacity tires with the ST GY.

I would upgrade. Your loaded weight will not be distributed evenly amongst all four tires. Most rigs have the heavy items on one side. On my rig when each wheel weighed when fiver loaded to 14,900 lbs the right front was 3,150 and right rear was 2,700. Left front 3,175, left rear 2,925.

The G-rated tires might prove adequate if they have sufficient margin. The RV in our signature, however, has a 16,000 lb GVWR and came from the factory equipped with G-rated LT235/85R-16 Goodyear G614 RST tires rated 3750 lbs @ 110 PSIG. We had tread separations with 2 of the original 4 tires within 3 months time, the second doing $2500+ in damages to the RV.

We wound up going to a J-rated 215/75R-17.5 tire and wheel combination that is rated at 4805 lbs @ 120 PSIG. Since then, we've had no tire problems at all.

Just our experience - YMMV.

You may want to see my full timer thread before writing the big check for the Redwood
