I was just wondering what the pros and cons are for tire truing

OB42TC3

Different foam diameters handle differently
Keeps fronts and rears even diameter
Keeps tires flat (or you can camber them)
Can repair tires when chunked by gluing in donor foam and retruing
Makes slightly out of true wheels runnable by truing the foam relative to the axle
Can make your own wheel tire combos, ex. 1/8 rubber on 200 mm touring wheel


It's just one of those tools that you need eventually, it will last years and years. Same as a comm lathe, 30 amp power supply and any competition electronics equiptment. High initial investment, but you'll have it for years.

Trued tires are faster, less prone to chunking, have more consistant traction , and wear alot longer...... I didn't believe it until I tried it for myself, but they wear alot less....

True, the smaller the sidewall on the tires, the faster they're going to be, and they will chunk less, but they will be less forgiving.

With a larger sidewall, you have more side to side flex in the tire, so you have more forgiveness in the tire, but they can chunk a lot easier.

Generally, you will find a diameter that you like for racing. But for practice, run them big so you get as much runtime out of them as possible!

Also, truing them can mean you can "overdrive" your car a bit (or underdrive) which means driving your front wheels faster than the rear (larger fronts vs. smaller rears) - this makes your car more "positive" through the turns - the fronts pull your car through the turn very nicely. With my nitro car I usually run about a millimeter of overdrive. . .works very nicely.
