Bolt on Steel Valve Stems for Sumec trailer rims

[gashog]

When upgrading from C load rated tires to D or E the low pressure rubber valve stems have to be replaced with high pressure Steel Bolt on valve stems. Just had my C's upgrade to Maxxis D's. Problem is finding steel bold on valve stems that will fit the Sumec trailer rims. The recess/counter bore is not large enough for these bolt on valve stems to fit into. Does anyone know where I can purchase steel bolt on valve stems for the Sumec trailer rims. Mean while I'm running a brass/rubber 125 PSI rated pull through that IMO is too flexible to use with my TPMS caps. Thanks..

There are 2 or 3 different dia steel stems. Napa usually has at least 2 of them.

Been to all the auto parts stores. There are two different sizes holes in rims, .625 and .453, the ones I need are the .453 hole, problem is the when you install them, the counter-bore on the face of the rim isn't large enough for the washer to go into ...(washer larger than the counter-bore hole)

Had the same problem with my 06 rims, just eliminated the washer, put the nut on and tightened from the back instead of with the nut. Had to use a screwdriver to hold the nut.

Ordered these, I believe they will fit Sumec rims and work great with my Tire Minder TPMS sensors since they are short. Will find out in a few days.

These Einky 3/4 Steel Valve Stems fit the Sumec Rims perfect and the TPMS Sensors are neatly tucked in out of arms way. With the rubber valve stems you can see marks on the rims where the centrifugal force flexed the rubber stems outwards causing the Sensors to hit the rim.

We did a little experiment while balancing the tires. The guy balanced one tire without the Sensor on and then re-checked it with the Sensor on. Adding a Tire Minder Sensor on a balanced tire will take the tire .50 ounces out of balance.

So, did you balance with or without the sensor? When I did mine, we came up with very similar results, so we balanced with the sensor.

Balanced with them on. Big THANK YOU for your suggestion to balance with them on in a previous post.

For reference, this style also works well with a recessed hole...

I tried that style, the recessed/counter bore hole on my type of Sumec Rims is also in the side of the rim. Hard to explain it not a flat surface. It's not a plain ole recessed hole its also in the side of the rim and there's no clearance for any steel valve stems that have the nut on the outside.

I need to find the time and drop by, I have lots of projects going on.
Best price I found on Maxxis M8008 ST tires was online at:

https://www.onlinetires.com/search/v...ds/page_1.html

I printed out their cost for a set of 4 shipped to my door and took it over to Discount Tires in Derby on Rock Road. They matched the price (actually beat it a little). Since they don't stock Maxxis they had to special order them, took a couple days. Beings they just opened up over there the work force is pretty green behind the ears, I made sure who I believe is the shop manager do mine while I hovered over him.. LOL... On the Tire Minders got them around 3 years ago they are OK, but I don't have a 100% faith in them. Will be looking for a better TPMS in the future..

I see that you already got your stems done, but for future lookers...I have the same wheel and standard 507 sensors. I used Haltec TV-575-HP stems which are 3/4" tall and use a top mounted nut. Purchased them from Grainger. I did have to grind the washers down to a slightly smaller diameter to fit in the recessed hole. Very pleased that the 507 sensors are tucked inside of the wheels.

Do you have the Einky part number? Maybe I can find locally.

They sell GY Marathons for $68. Nice price.

They came in a Ziploc bag without a part number, so they must buy them by the hundreds.

When I replace my Tire Minders TPMS, I'm likely going with this setup:

TST 507RV 4 Wheel Towed Vehicle System w/ Cap Sens & Repeter for Sale Online - Vulcan Tire Sales

$288.00 is a good price and even comes with the repeater (signal booster) which I don't have with my current setup, but probably need.

Army/Navy (AN) washers are small on o.d. and are available at anywhere aircraft are maintained and some hydraulic hose outfits.....some speed shops also.

Einky refers to a style of stem ("A high-performance "No Show" type chrome plated valve that installs from the outside. A rubber washer and nut are on the inside.". The part number changes from brand to brand, but "VS-8" seems to be fairly common among brands for this style. The Haltec part number for this stem is TV-6010.

You can just call around and ask for 3/4" straight Einky style stems, or just order this and have 16 spares!

Thank-you. Found them locally at Midwest Wheel. Ordered Maxxis M8008 "D" tires today at the local Discount Tire and have the TST TM-507 in the box ready to go. Tires were $106 each. Have 8 sensors for mounting on the 2500HD truck and trailer. All I needed were the valve stems. The folks at Discount Tire never heard of the all metal bolt in stems. Anyone need some brand new stock Flagstaff tires? Cheap! I will feel much better with the new tires vice the China Bombs.
