Tires.. What's the diff??

[Zjor76]

Quick question..

Is there a difference in compound/traction between;

• M Chassis Reinforced Tires Type-A #53340
  

And

• M Chassis Super Slicks #53222 ??
  

Which one is grippier??

Apparently both are 60D's.

  

Cheers for any advise!! []

The m-chassis super slicks are the old low profile tyres (not 60D) so will reduce top speed if used on the driving wheels. i think they are slighly harder/ less grippy than type-a's which are VERY grippy.

Thanks for taking the time to post your response!

Looks like a set of Type-A's will have to go on order.

Cheers,

Is this the same case with the 53215 M-Chassis slicks? Are they lower profile and a less-grippy compound? I'd guess they're not as desirable since they're half the price.

OP-215 are 55d and are not as grippy as the 60d Slicks but are the perfered tire for Tamiya racing here in Japan. The 60D have more grip and can cause the M03 to roll with the higher center of gravity. Also they and can take alot of the smothness out of the driving one thing you really need for Tamiya racing.

The 53215 tires were on all of the cars at the big Mini Freak race that had 80 drivers.

Great info -- thanks. Are they a smaller diameter as well, therefore limiting top speed, or just a different compound? Is the diameter what "60D" and "55D" refer to or is it something else?

The diameters are literal, so a 55D is 55mm in diameter, the 60D is 60mm in diameter.

OK. I wonder if the increased grip (vs. stock tires) would do more good for my lap times than the smaller diameter would hurt. The track I race on is tarmac and there is one long straight but several spots where you're flat out with the silver can we have to run. Traction rolling hasn't been a problem for those on slicks, even with a treated track. I'm probably best off with the 60D slick for the top end and a bit extra care in the fast tight corners.
