help with wheel hardware size spec

Ryebread · 10-07-2015, 01:06 PM

does anyone know of an app online where you can set your current wheel spec and length of bolts, and enter your new wheel spec, and it tells you what size to get? I'm brain dead right now and I'm stumped on what hw to get. cheers man

p.s. in the event you're good with this stuff...

I have new wheels for my winters, et 43. 19x8.5.

old winter setup 18x7.5 et 51, but I was using them with 8mm spacers. 51-8 = 43, same offset as my new wheels.

but the new wheel is 1" wider total. and I dont know what to do from there. divide by 2? and get 12 or 13 mm longer bolts? doesn't seem right.

thanks

Changing wheel specs doesn't have affect to bolt length. Only when you use spacers you need longer bolts. Basically your new wheels most likely will work with your stock factory bolts. Sometimes some wheels require different kinda bolts, but length is still the same as factory bolts.
