Dirt Quake Rubber

On the run-up to Dirt Quake 1, I recommended the Mitas Speedway rear as perfect cheap option dirt track tyre. One of the only drawbacks is that it's not road legal. As I'm planing to get an MOT for my chop but want to maintain the bobbly* look, this Taiwanese trail pattern Cheng Shin seems like a good choice. Unlike a motocross tyre, it has the same razor longitudinal cuts as the speedway rubber which give some extra flexibility in the knobs.
At 3.00 x 19" it's slightly narrower which makes for better handling on the street too. It cost me £50 at Kempton (which in retrospect sounds a little dear). I haven't tried it in action yet but the compound feels nice and grippy - unlike the perished and hard speedway cast-off I ran last year.
Your back tyre isn't so crucial if it fishtails in the quagmire but if you want to keep your pants soil free, it's most helpful you have a well planted front-end. BP

* Bobbly is a term first coined by Skooter Farm Dave in Milan a couple of years ago when he took note of the nouvelle vague choppers with motocross tyres - ie bobber with knobbly tyres. This Evo' built by Benny Boneshaker is a perfect example of the genre.

Mitas Speedway Rear

'Made in Czech Republic - British League - Not For Highway Use - Mitas Speedway Rear SW-07 3.75-19'
These tyres you can find discarded at the perimeter of any UK speedway track. At the hands of a methanol burning pro they will only last one race before they're shredded, two if you flip them. Anything with more stubble on it than a 2.5 x 19 ribbed Avon Speedmaster has got to be good to stop the front end of my XS washing out at Dirt Quake. For the rear I'll stick with the 3.5 x 16 Avon Speedmaster with its Fruit And Nut chocolatebar tread pattern. If I was feeling a decadent cheat I'd go for full bobbly spec MX knobbly on the back. BP
