I think the 40 series were originally made with the idea that it would be good for the track... less sidewall flex and more tread on the dirt. I've never raced them myself... but I know for a fact if they were the best racing tires then that's what you would see at the track.

IMO, the "tire guide" thing would read like a 100 page spreadsheet... information overload. There are too many variables... tire size, tread type, compound, surface type, condition, appllication, etc, etc... and just too many tires available period.

Rough and blown out tracks like a little more flex in the sidewall, and vice versa for a smooth track with good bite... less tire flex.

So regular maxx sizes may be better for rough or loamy tracks and the MT for good conditions, in general. The MT's will have quicker response it there is good bite.

Tire compound can be tricky... you never know what's best at a particular track without trying them. I would check with the racers and see what they like (where you race most). Sometimes it doesn't matter at all and sometimes it make s big difference.

I have only raced (recently) with the MT bowties and I have a set of regular bowties that need remounted, so I haven't run them much.

I like the looks of the Crimefighters and Holeshots better though, so I will be getting those if I keep my truck and do some racing next year.

For buggy I run Crimefighters also... they work pretty well at any outdoor track I've seen.
