Do I Need to Replace Valve Stems When Going From Load Range E to Load Range G Tires?

Question

Question:

Erik has recommended me abovePart # PRG80235 in reply to my question of Jan 5 upgrading tire ST235/8027R Load range E on my fifth wheel . I gonna replace front axle tires 2 tires first and rear axle tires later on. I understand above tire PRG80235 has 8 bolt pattern wheel and max pressure of 110 psi. In this point, a Can I mount above tire by using my current 6 bolt pattern wheel 6 lugs because wheel hub of above fifth wheel has 6 bolts only. In this case, do I need to change valve stem to accept higher air pressure of 110 psi? Can I get new valve stem suitable for 110 psi for my current 6 bolt pattern tire wheel? Would appreciate your reply ASAP. PS. Please advise the weight of above tire with wheel Thanks.

While there are tire/wheel combinations available using a 235/80r16 tire, you are able to use the tire only # PRG80235 with your existing wheels instead of the wheel and tire combo. As you mentioned you will need to swap out the valve stems to accommodate the higher pressure rating on your new tires. You'll want to use the Americana Metal Bolt-In Valve Stems # AM20906, which are rated to be used with up to 200psi.

Most tires at this size have a weight of around 35-lbs and a total weight of around 60-lbs when you add a wheel into the mix. For example, the # TA39VR, which is a tire and wheel that will fit your Cedar Creek 5th Wheel, weighs in at 58-lbs total.

Since you're also looking for a spare tire carrier that will fit on the rear bumper of your 5th Wheel trailer, I recommend using the Bumper Mounted Tire Carrier # TR-1, which is designed to fit on 4" x 4" box bumpers and is compatible with most 15" or 16" wheels. This carrier does not have a listed capacity, so you'll simply want to make sure that your rear bumper is rated to carry up to 60-lbs or so in order to determine whether or not this will work for your trailer. The Ultra-Fab # UF15-954730 that you were looking at is only rated for up to 60-lbs, so you're going to be right around the capacity. For this reason I would go with the # TR-1 over the # UF15-954730.

Answer 8

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…
