Schumacher Block tires

[AfroP]

A few people have commented about the Schumacher block tires for indoors at Seaham.

by all accounts they provide as much grip as the yellow mini spikes and have the added bonus of less wear.

but what tires would you use on a 2wd front if you were to use Schuey blocks on the rear?

4wd is sorted as you have the front and rear.
would the 4wd fronts work on a 2wd?

or would it be a switch to cut staggers? or maybe even Dboots block pass?
