19.5" Tire Selection

[AH64ID]

I got my M608Z's mounted yesterday in 245/70R19.5. They have about 50 miles on them and I am very happy with them.

They are smooth as glass at 70-75, using counteract beads. They really made the truck more stable, not quite as much as the rear anti-sway bar did, but very noticeable. This is all at 50 psi at a GVW of about 8800-8900.

Those look NICE on your truck...are you running steer tires all the way around so you can rotate them, or...???

Also, can i ask bout what they set you back per tire online or locally?

 

[AH64ID]

Thanks, I really like the look.

After tax about $630 a corner mounted, counteract beads, and 2 open center caps.

I got the wheels off ebay and tires locally at Les Schwab. I tried to give Schwabs the wheel business too, but the best they could so was about 40% more.

Nice. I might have consider going to 19.5's when the time for new tires comes around.

The spare is in. It's heavy, but not too hard to get in there. The sway-bar and Class V hitch don't leave a lot of extra room. With the MH diff cover I have to pull the tire aft about 2" to clear the diff cover if the suspension travels more than 4".

Thanks..so are those Toyos all position or all steer or a mix??

I hope that you use some sort of tie off for the spare in addition to the factory lift mechanism!!! Since the steel 19.5 wheel/tire comco weighs probably 30# more then the oem 17", I have added a 1" ratchet strap across the spare to the frame.

They are a drive tire, since both axles drive

This is probably the most common Toyo on a pickup in 19.5" setups. Aside from a 2wd DRW I couldn't see a good reason to run separate tires front/rear.

I don't. It's about 34# heavier than the heaviest OEM setup (steel DRW wheel w/ 235/80R17). It pulls it up there with ease, but I might add a safety strap.

I am hoping to pull the trigger on some 19.5" wheels and tires in the next month.

I am going with the Vision Type 81's in black and a 245/70/19.5" tire.

My tire choice is down to the M608Z from Toyo or the G-622 RS from Goodyear.

The big benefit to the Toyo is that there is a Les Schwab everywhere around here, and not as many Goodyear dealers.

Does anyone have experience with either, or both?

Thank you.

Does the Vision wheel have the zero offset? Does it fit in the wheel well?

How are the Toyo's wearing?

Any issues with the one ply sidewall?

Experience any issues with the higher weight over stock tire/wheel?

 

[AH64ID]

Yes there is zero offset to the vision wheel, but it hasn't posed any problems yet. It could cause fitment issues with 265's and stock length control arms thou. There isn't quite room for chains with the 19.5's.

The Toyo's are wearing ok, but they see a LOT of dirt/gravel road towing so that will wear any tire fast.

No issues whatsoever. They are quiet, smooth and handle the weight well.

The only drawback to having a 1 ply steel sidewall is there is a minimum pressure than can be ran. I can't go below 70 psi for sidewall integrity as well as bead retention. I don't find it to really be an issue thou.

 

[seafish]

Thanks for the update…how many mile on them so far??

I am really leaning towards them, as the only other tire I all consider is the Michelin XDE-M/S, but it looks like they may have stopped making them in 19.5 sizes, which is really too bad.

DO check out the "rectangular bead bundle" (#6 on benefits list) on the page link above, as I believe it directly affects your concerns about the lack of such a bead on casing fatigue/life on the Toyo M608z and other 19.5 ties. WISH I could find out for sure if they are available in 19.5 anymore, but Michelin no longer answers phone inquiries on commercial ties, inly directs to their website, which is NOT showing them in 19.5.

 

[AH64ID]

The bead issue is more with 19.5" (well any xx.5") wheel design. There isn't the standard "groove" for the bead to sit in that passenger vehicle wheels has.

Most 19.5's are regrooveable/retreadable, so the casing will last a LOT longer than the OE tread.

I have around 9K miles on them.

I think I will look more into the M920's next go around, but I am certainly sticking with 19.5's.

I'm running the Michelin xds2 on all four corners and love them. I rotate them between 5 and 7k miles, keep 100psi in them and they wear great in my eyes. I see a lot of gravel roads and job sites.

I was just looking at those as it turns out that are what Michelin offers to replace the XDE-M/S in the size that I want…

Curious how long have they been on your truck?

How many miles are on them??

How much wear left??

Any chance you could snap a pic of them on your truck??

TIA!!

I have stock wheels plus Bushwacker flares up front but would like to know how far the wheel/tire will push out with this wheel. Do you have any photos of a front wheel? No issue with the rear because I have a flat bed.

The Rickson wheel has the correct offset but the weight goes up with the steel wheel. What is the wheel/tire weight limit for our trucks?

I need to chain up at times during winter so was looking at 245/70R19.5 at the most. I have Carli control arms and currently have about 4" clearance running Hankook Dynapro ATM's which are 31.5." Your tire is 33+" so I think I should have sufficient clearance when I chain up. Agree?

I have replaced two tires this past year with less than 1000 miles due to sidewall punctures. Was hoping a LRG would be a little tougher tire.

Thanks for the info!

 

[AH64ID]

My 255/80R17's are the same overall size as my 19.5's and they fit chains easily. The offset of the visions is what removes the room for chains, but 1/2"-1" longer control arms would do the trick.

Not sure on the weight limit, but they are heavy. I have upgraded ball joints and wheel bearings.

[CVR222NV]

Thank You! That doesn't look too bad. I think I have a bit more flare than your set-up. Much better looking wheel than the Rickson ... and less expensive ... and weighs less. Now I need to see a Rickson wheel just to see the difference.

I'm getting ready to install a Detroit Tru Trac, Dynatrac Free Spin kit, and Carli ball joints so hopefully that set-up will handle the additional weight.

What free spin kit are you running?

 

[AH64ID]

I have the Yukon kit.

I purchased a set of 19.5 x 7.5 Rickson wheels with Hercules H-702 tires - 245/70R/19.5 - off Ebay. These were not the tires I wanted but the deal was so good I basically got the tires for free!

This is a closed shoulder tire with a lug design in the center. Does anyone have any experience with this tire design off road? They sing a bit on the highway but run super smooth! The PO had the tires trued/shaved and high speed spin balanced on his truck but I don't see any need to check the balancing on my truck given the results of my test run.

The wheels fit nicely under the front wheel wells! Won't have any issues with slinging mud.

I have 3 1/4" of clearance at the back of the wheel well with the 245/70R/19.5 tires. At 33" I definitely cannot run any bigger tire and still get the chains on.

Just checked the tire pressure and the PO had them all at 60 psi. I thought I read that the minimum psi should be 80 for this type of tire. Not sure if this is what he ran unloaded or if he aired them down for storage. Any thoughts?

You are correct in that you definitely do NOT want to run 19.5 tires under pressurized for the simple reason that there is no bead lock that hold the tires onto the rims and ALSO excessive sidewall flex from low pressure can and will eventually lead to sidewall failure from fatigue.
The industry term for it is "Sidewall Zipper Failure" which obviously cannot be pretty.

I am not sure what is the lowest pressure you can run in YOUR tires (it differs mostly by size, but also by manufacturer). For instance, when unloaded and not towing I can air down the 225/70/19.5 G tires on my truck to 70 psi based on the load inflation chart, and IIRC one of the Michelin 19.5 tires (forget which one can be aired down to 65 psi) but that is the lowest I have seen for these tires. I highly recommend finding the load inflation chart from the manufacturer for your tires and air up accordingly. Meantime, I owuldn;t run any less then 75 psi UNLOADED and more if you are running loaded/towing.

All that being said, keep us updated how those tires work out for you mileage and ride wise.
