Aspect ratio HELP!

Does anyone know of a tire with a decent aspect ratio for a staggered setup? Everything seems to get smaller the wider you go. It's fucked up to run 275/40zr20 fronts with 305/35zr20 rears. I can't find anything decent for the rears. I'd really like to try and find something with a 45 or 50 aspect.

um... 305/35/20 is taller than 275/40/20....

aspect ratio on a 275/40/20 means the tire is 40perecent as tall as it is wide. the aspect ratio has to go down the wider you go to make it the same hight.

a 305/40/20 or bigger aspect ratio would way taller than you want to go.

normaly for every 20 you go wider in the tire you go down 5 in the aspect ratio to make the same hight
example 255/45/20 will be close in hight to a 275/40/20. thats why we use that size.

Lol, jontoad. I'm a dumbass, hehe. Been driving myself nuts with this all day. I couldn't figure out why tire sizes got smaller aspects on the wider ones lol. thx bud!

Would a setup like this work? NTO5 275/40zr20 front 315/35zr20 rear The 315 calls for 10.5 in. min. rim width. Would that still be safe on a 10" rim?

thats what i want to run next summer. im gonna get a set of 10 wide vipers for the rears with 315/35/20's. when i go to the autocross ill swap my 9inch wheels back on the rear so i don't tear up my street tires.

i was actualy gonna ask adam if he would just sell the rears if you didn't buy them. lol.

yea you should be fine with that setup.
