38" with stock spare

[lasvegash2]

i am currently putting 38" on my h2. will the stock tire work as a spare for either front or back or will it mess something up being different sizes? also, being different size, do i need to reset the computer with the superchip or can i run it stock for awhile, knowing that the speedo and mileage will be off.

thanks,
scott

You'll mess things up.

I haven't reprogrammed our computer, but I should. It'd be better for mileage and speedometer acuracy.

Yup. Unfortunately, it will also correct the odometer.:rant:
