Here is a dumb question from me even lol

Baja,

 

do you want widest or tallest?

 

will depend on wheels you are running...

 

I would think a 175/80R13 would give you the best heigh while still keeping you from rubbing the rear trailing arms... I have had gen1 brats with 185/80R13's as well.

 

you can go a bit wider if you go with something like the 4 slot alloys from 1974. they have smaller backspacing, so the tire is pushed out further from the chassis... I ran some BR60-13's (205/60R13) on a set on a 78 Brat for a bit....

Jason, why are you looking for bigger, wider tires? Bigger is not always better. On snow and ice, narrower tires are a significant advantage. I'm not an expert on tires for RallyCross but I'd look into what works best on your car and on the varied conditions that you might encounter. When I first started running with an older wagon, I found I got my best runs with a "normal" set of 175/70-13 Hakki's; then I found they weren't legal in Production and went to other tires. Ask around in the rally circles; try the two guys who seem to win consistently in Production with their Justys. I'm certainly not the expert here but I'm not convinced the wider is better theory applies here.

Ed I was just wondering cause if I do get this other wagon I want a set that will interchange with the both of them and the only 2 choices for tires from Kumho for actual rally tires in 13" are 165/80 QR13 and 195/70 QR13's here is the link to the page with the info http://www.tirerack.com/tires/tires.jsp?tireMake=Kumho&tireModel=ECSTA+R700 and for $68 for a tire that can't be beat for new Rally tires :D and oh yeah Mick you didn't notice I do have those alloys on my wagon right now :burnout:

wider is better really only applies to heat buildup. On pavement or rocks wider can be better because more surface area means more capacity to take heat before they burn. On the dirt it doesn't matter much because you have the same amount of weight pushing on the ground, just a higher pressure contact area. For snow or water thin is best because you don't have to push as much water or snow out of the way, and you will sink to hard ground faster.
