well im thinking about grooving my tires on the yota heres what pattern I got so far

 

any one got any other patterns I should try

 

I don't think I would groove an A/T. Sipe it, maybe, but I'd be too worried about destabilizing those center blocks. The Geolandar A/T (I love that design--wish they still made 'em) has plenty of biting edges already. I think it'd be too likely to increase the chance of tire damage if rocks get wedged into the grooves. Perpendicular grooves like that are also likely to increase noise.

Aside from dirt-track racers, I think the only other grooving that makes sense is on large-blocked mud tires without sipes, like the original-style Swampers.

 

more noise the better lol

I grooved 2 other sets of all terrains and never had a problem with stability.. these tires suck on wet roads so I was trying to get more grooves and biting edges not to worried about rocks all we have here is beach sand on 80 percent of our trails

 

I would sipe the edge blocks, maybe 3 per block. use something small like a razor or the smallist dramel cutting blade. If it is wet traction you want, sipes is what you need.

 

well I stared grooving with my ideal tire groover I got 1 tire done.. I already siped them if u look at the top of the pic u can see the middle blocks have 2 sipes in them.. tread pattern looks great with the grooves in them

 

I'd vote to sipe the outer tread blocks as well, if you are looking to improve wet traction.
