OK, correct me if i'm wrong... i counted 4 60D's : normal stock 60D, S-grip, M-grip, and Type A

What's the difference between them grip-wise? i know they look different.

Stock 60D = "kit tire", treaded = not race worthy?

S Grip = "Super Grip" treaded tire

M Grip = "Medium Grip" treaded tire

Type A = slick, not sure of hardness or "grip-iness" relative to S grip and M grip

For carpet on M03m, I use S grip in front, M grip in rear.

Speaking of tires.

I ran some "older" tires over the weekend and really liked the way they handled. I then put on brand new tires, and my car pushed like a dump truck. Is this normal? Do they have to break in before they start working? Is there a way to quicken the breakin process?

Thanks

Type A Slick will work on Carpet...You have to stay in the groove. I believe the A slick is like a S Grip

The stock kit tires, I heard last year the guys were using them for the Novak Race.

For some people the Threaded tires have worked for them because they clean out better than the Slicks.

Takt,
The New tires will need to be scuffed in.
I would believe they would get better after a couple of runs.
Also the track needs to have a good groove to for them.
I know Monroe is new so could be one of your problems too.
What compound are you using at Monroe?
I hope this helps

I am running the s-grip and m-grip ...same setup as Trackside. With the "old" tires, it turned very well. New ones not so much. You are right, Monroe doesn't have a groove yet.

Is there a way I should scuff the tires? Run a dremel across them or sandpaper or something? Or just run them until they come in?

Thanks

I have definately noticed a difference in old and new tires. For whatever reason the old worn tires always work better for me.

One way of scuffing the tires.
Is do a burnout on your driveway, rotate tires(front to rear) then repeat.
When I scuffed my Type A's in, I just ran it at Trackside.
It took about 4 or 5 runs for the tires to get the grazing off but it worked.
The slicks you can not do the burnout on the pavement. The S & M Grips have a little more meat to the tire than the slicks.

I would use the nice smelling Paragon for Monroe to get the tire's scuffed in.

From reading this thread in the past, I determined that the new tires are not made the same... some specific chemical in the rubber recipe was banned, or something along those lines. I think this holds true for many, if not all of the Asian RC tire manufacturers. Retrace this thread, the posts are back there somewhere... or Tony might chime in & confirm.

I just opened a new old stock pair of standard m-chassis radials(55d for the M-01 - not 60d) with the old packaging, and a brand new recently-stocked pair of the same part number, and they are completely different. The old pair from the mid-90s is very soft with a white residue on them, & the brand new pair(same exact part number, but with a new hang tag label) is stiff, slick & they even have a much stronger smell. The new tires feel like vinyl

Questions from a Mini newbie:

My friends and I have started our own small Mini basher racing series, and we were thinking about running regular touring car size wheels & HPI X-patterns since they are readily available at the local hobby shops in our area. Tamiya stuff is scarce around here.

Are there any pros & cons of running touring car size wheels & tires on the Mini??? (Other than having to cut out the fenders a little more.)

Should we change out the pinion?

One of our racers said we should run HPI 31mm Vintage wheels & tires... I say no... they may be a little too wide and affect performance badly.


Thanks!

Probably since crude oil is near $100 a barrel, they probably changed the 'recipe' to more vinyl in order to save some money. The older tires might have had more of a petroleum rubber base to them.

The situation as I understand it, is that there was a specific compound that nearly all the manufacturers used in their tyres that was identified as being somewhat 'nasty'
Not necessarily to the end users, but earlier on in the manufaacturing phase.

Hence the fact that nearly all rubber tyres have now changed to some extent. There's no question that they're different now.

Touring Car tyres on Minis? OK for mucking around, but it stuffs up the suspension geometry big time and the car handles like crap....

A mate of mine had a mini with TB02? susp arms, touring car wheels run by 5.5 brushless. Handled great went like a bullet. Downside was after a while gears sort of wore out.
