Thanks for the temp tip.
These tires/wheels are 88mm in diameter. The OE tires are 98mm diameter. I'm thinking the motor will require less torque to spin them at a faster rotation. Hopefully that will result in cooler ESC and motor temps. Your thoughts Mike?

The glue I ordered to mate the tires to the wheel rims is: Team Losi Racing Tire Glue. The bottle says "instructions included".
I'll share pics as I finish mounting and gluing.

While you have the time, brush up on how to mount and glue correctly. Its not hard but its also easy to mess up.
I think you are correct as far as the temps go. I also don't know your kit well at all. Watching temps is cheap insurance.

I bought one similar years ago for my nitro cars. Its prob one of my most used, rc specific tools now. (except hex drivers! )
I use a temp gun for 1:1 diagnostic too. Handy little things!!!

I received the tires and did not realize their were two sizes in the package. Two were slimmer and two were wider. I glued the tires on the rims. Mounted the slimmer tires on the front as those appeared to be "steering" tires. The wider tires went on the rear axle. I went to smooth asphalt parking lot and did my first run with the new tires. Wow! The steering was really responsive and turn radius greatly improved. The acceleration with the stiffer wider rear tires was like a sling shot! No tire flexing and tire hopping.

Typically, 1/10 scale 4wd buggies will use two different widths of tires. The first time I've seen those tires were way back when... on DHK Wolf 1/10 scale 4wd buggy.

They are good tires... if you want a longer lasting medium compound knobby. The foams they came with didn't last. After a few uses, the open cell foams disintegrated and flung out vent holes.

Thanks for the tip. I see outer foam insert's sold that could substitute for the OE tire foam in these.

I believe vent holes in the tire are not good. Seems they would let dirt and moisture directly into the tire and cause the foam to deteriorate quickly.
I looked at the OE large tire in my Post #10 and I finally found two vent holes in the rim rather than the tire. Squeezing the tire, I can hear the two holes releasing air. The rims appear to be glue sealed well and do not appear to be releasing air. I'm going to try to seal the two vent holes in the rim with liquid tape. Then they might perform similar to a pneumatic tire. Image of OE tire attached with blue arrows marking vents.

I have several cars with non foam inserts. All have one or two vent holes in the rims.
I began working to convert them to a semi-pneumatic tire. My method described here worked.Here's my method if you want to try it.

1. Locate either one or two of the vent holes in the rim. If you have run your car in dirt and sand, there will be considerable dirt-sand debris in the tire. Squeeze the tire briskly to vent the debris out of the tires. Rotate the tires and continue squeezing them until no debris comes out.
2. Take a cotton swab, soak the tip in rubbing alcohol. Clean the rim surface around the vent holes.Take a tube of Liquid Electrical Tape and place two coats of the tape on each vent hole. Allow 30 minutes between coats. Allow all to cure 24 hours. After curing, gently squeeze the tire. You will notice the tire feels similar to a foam inserted one.

I'm assuming they are preglued tires. Any, and all preglued tires that I ever came across did not have vent holes in the tire itself... they all came with vent holes in the wheel.

Great job at sealing those vent holes. I do similar with E6000, but I do put vent holes in the actual tire before using. If a person runs their toys hard enough, and tires are not vented, air will eventually get pushed out at some point.

If I purchase preglued tires, I'll use a soldering iron with pointed tip to melt two holes in each tire. Soldering iron is quicker for me and no chance of tearing a tire. For tires that are not glued yet, I'll use a leather hole punch to make the vent holes.

Where a person places the holes on their tires... that's up to them. I do two holes (approx. 3mm) in each tire on the centerline/180* apart from one another.

The tires I modded here were preglued and the rim to tire contacts were tight. To add information about the debris I was squeezing out of the tires, it was almost 1/4 teaspoon mix of fine dirt, sand, and small black particles. My guess, the black particles were from the sand..sand blasting the inner surfaces of the rim. Not good.
I used the Team Losi Racing Tire Glue with it's needle fine applicator and the red tire bands in my post above.
Overall, that application worked very well.
If I get more wheel/tires with rim vents, and the preglued rim-tire, I'm going to continue vent sealing the rims before my first runs with them.
IMO, I would nor consider poking vent holes in the tires.
