tire calculator

hey, i like the calculator thats on here too, but when i was deep into the MR2 world I found a calculator that was awesome, it showed the wall view and tread views. it also did the rim calcuations so you could see how far the tire would bulge off the rim. it had everything, even the specs of the rims you put in so you can see the measurment of the offset of the rim. it was very helpful in helping me choose the rim size to put on my widebody mr2,
does anyone know where this is, i lost the link to it.

 

ooopppsss,,, found one like it. see what you think

yeah, it helped me to be able to measure how many inches i had on my MR2 from the brake disc/hub to the outside of the fender, so in the case of the Tacoma, i need to see what offset i need to clear my UCA, measure from the hub in from a plumb line and see how many inches i have to work with, then input it and play around with some of the different offsets to find what is the best.
