Just go to Walmart.com, in their search bar, place Uniroyal RS20 and your tire size. It will pop up

It also makes perfect sense to have the alignment checked "under road load".

Alignment or RUN-OUT and BALANCE?

Some truck alignment shops are starting to do a loaded toe in adjustment. Instead of just after being sat on the lazy Susan trivet plates.

Wow.  Would love to see that equipment. Who makes it?

Thanks.

I was reading about that process a while back. But can't find it right now. The theory is that front suspensions while at rest do not impart any stress to the tie rods from the toe-in setting. When underway. The forces of rolling down the road puts outward pressure on the tie rod and can thus increase toe-in to out of tolerance levels. So the process is simply to put a load bar on the back of both front tires to simulate the force imparted by toe-in while driving. Then check and adjust the toe-in.

If the load bar changes the toe-in setting I would argue that the tie-rod ends are worn....

Just my 2 centavos

Putting on my Toolmaker's apron, making sure I have my 1" micrometer, my 6" steel scale and my pencil.  And a clean shop rag, all in their places.  OH, and my glasses,

Nothing is rigid.  absolutely nothing.

When it comes to a front end suspension, all of those moving parts have built in clearances so that they move.  So yes, we set a certain amount of toe in when the suspension is adjusted in the garage*.  And yes, when driven down the road the front wheels are sprung out against all of that built-in play to a more or less straight ahead position.

It is my opinion that pulling in on the rear of the front tyres to simulate road conditions is akin to snake oil.

*We used to have our own alignment rack in our garage.

I dismounted my junk michelins (I had two inner rear duals blow holes in sidewall) and mounted my toyo m177 myself at home. I got the ken-tool Serpent bars (price has gone up since I bought them).

I also got the slide hammer bead buster, but I didn't need it on the aluminum rims, the beads all slid off easily by standing on it. The steel wheels took some beating.  I replaced the two steel wheels with aluminum. I have 6 alum rims and 1 alum mounted spare now. Anybody wanna buy my steelies with mounted tires?

I did not balance...because I installed centrimatic balancers. It rides smooth as silk.  I measured the tow and adjusted slightly for good tracking. I found that going by feel to dial it in is the best (assuming it isn't far enough out to cause tire wear).

I do appreciate all your thoughts and feedback. Ended up purchasing Michelin X Multi Energy Z (H rated) STEER tires all around via the Prevost Dupree Michelin tire discount program. Tire clearance good all around. Had tires balanced with beads. Drives and rides great! On the road again!

Uniroyal RS20's from Walmart.com!!!! Owned by Michelin. Dealer told me your getting Michelin quality at a 40% discount

I've attached the Uniroyal commercial tire inflation book. For 275-80-22.5, 110 lbs., that takes you to 22,750 on your rear axle, and 12,350 on the front axle.  This seems a little high, so I would at least weigh sometime when fully loaded, at least they recommended a safe pressure.

The Uniroyale tires will be fine, they are not the same as the Michelins in the previous post. Many are happy with the Uniroyale brand as I am with my Toyo tires. Most replace the tires because of age and not wearing them out. 

Toyota builds both the Lexus and Toyota brands. No knowledgeable, honest salesman would say your getting Lexus quality in your Toyota Corolla for 60% less. Different design, materials, and assembly criteria. What you were told is called "a pitch".  No worries though, correct air pressure, equipment mechanical condition, and road conditions will, as with any tire, be important to you now that you have new tires.

Don't agree at all but that's ok, If you want to pay for a Mich, you can! Mine will age out before wearing out, so it's not worth it. I would challenge you to go look closer at Toyota and Lexus again. Your paying for a name and a few more gadgets, not the quality of the build or parts. Japan has it figured out. Make a quality car no matter what the price

Agree. Toyota products take a beating with contractors, etc. Less likely to get garaged. Lexus is great but Toyota is right there with them. Our RAV4 has 240K on it with only brake pads and one battery in many years of ownership. No timing belt to worry about.

Least expensive RV ownership would be a Toyota/Lexus Land Cruiser/Sequoia/Lexus GX/LX 470 pulling a rebuilt older Airstream. Tires would be about it.

Bob & Susan,

We are only interested in Michelin tires and have been happy with XZA3 LR-H.

Since XZA3 are no longer available and if price is not a factor, what Michelin model do your recommend from the current lineup?
 
Like others we use FMCA to get their Fleet price

Thank you,

Barry and Cindy I notice the new Michelin "x" energy Z tires "h" rated  max out at 7160 pounds at 120 psi.

My Xza-3+'s were 7610 at 120. 

No longer offered. 

The new tires  hopefully should have similar ride and handling qualities and the higher pressures needed.

Most do not live in so cal with bad roads. 

I would buy them no problem

Hopefully I have attached the Michelin X-Line Energy Tire Chart pressures for anyone that may have an interest. I had my 99 U320 36ft no-slide FT weighed loaded with normal supplies ((10,300 (5,100/5,200) front and (19,500 rear axle weights)) and added 1,000lbs for people and fuel, propane, groceries, bay storage supplies top offs plus a little margin. Similar approach with my H rated tire pressures (105 on front & 100 on rear tires which allows for cooler/warmer ambient temp variances without having to adjust pressures every morning...). It does not ride rough but may reduce tire psi over time as I gain more experience with this set of tires.
