I would set the ride height to 7.5mm both front and rear on 64mm diameter, then depending on the length of the heat I reduce the front tyre diameter by an amount that will finish the heat at slightly less than the rears.
What I'm trying to say is that the car will be a pig if your front tyres are larger than the rears and it puts too much strain on the drive train.
Woot..... sorry, I don't have tyre truer, so I have to use as is

but are you sure about kawahara / zac's tyres diameter F/R is different ? Thx, I don't notice that until now. What about using smaller / higher pulley at front ? so I don't need to put extra attention with belt strain / drive train issue ?

asw7576,
Sorry, you'll find there is no escaping the need for correct tyre sizing.
You will need a tyre truer or to get friendly with someone who has one.

..... umhh..... how about shaving only the front tires until it gets smaller diameter than the rear ? I think that I'm going to do. I'm surprised that mtx3 have drive train / belt strain issue.

"get friendly with someone who has one. "

Ha... ha.... ha.... nice one! actually there are nice people in race track who could lend me tyre truer, but I don't want to..... I just drive and go.

All these guys are right. At some point you'll have to true down at least your front tires. You'll notice a HUGE difference

heres a tricky one. IŽd like a couple suggestions on how to obtain even wear on untrued foams using one way and stock belts. for instance. 35 front 40 rear, etc etc
here are the issues. I do not have access to a tire truer, prices of foam here are about 39 a set. I do have the kawahara conversion but puts too much stress on the front and side pulleys and the belt is low friction but with low life. and finally, I suppose that If I use front diff the wear will be even now right.? suggestions appreciated!

You will never get a fast set up that has perfectly even tire wear.It just doesnt work like that.
Where do you live? You can get great tires at a low price here in the states. WWW.RCTexas.com This guy also carrys a low cost pretty descent tire truer,made by G.Q.
As far as the pullys, I have always used the stock ones.Do you run on a permanant track or a Car Parking lot?

Default re: tyre truing

Hiya,

I never true my tires in my MTX 3 ( i do in 1/8th !!!)......Found that trued tires did not affected lap time that much...actually i was quicker with tires out of the box rather than with the recommended split. I normally uses one set front to three set rear ( tired kawahara conversion 16/19...rear still wear at the same rate....hence gone back to stock setup.....


There are some good drivers at my club, whom will always truing their tires. i am not exactly slow at my club, as when i race with some top drivers such as mark green, i would be second and about 0.5sec behind.

Can any other MTX 3 owners out there verified that truing tires had not made any different to their lap times, and some explanations why not ? Coz i don`t know why....whereas in 1/8th it`s very important !!!


Thanks
