Hey, I'm pretty new to the whole wheel and tire thing but I was wondering if anyone know the actual bolt pattern for a 2010 IS250 RWD? I did a search and some people said it was 5 x 114.3mm? Just wanted to ask around. Thanks!

 

thats correct...

last I checked, all Toyota/Lexus 5 lug vehicles, except LX series and LS460/600's are 5-114.3

 

Thanks a lot. So 120mm bolt fitment on some wheels wouldn't possibly fit I guess?

 

correct... you need 5-114.3 or 5-4.5 (the exact same thing)

 

yeah 120 is bmw i believe

 

yup... and 5-120.65 is some Chevy... 5-4.75 actually... completely not compatible with 5-120...

Would probably work, but who knows for how long...

 

Thanks a lot. So what does it mean when a fitment is universal? how is it able to fit all cars?

 

its not truly universal as the word means itself...

usually when a wheel is a universal fitment, it has two sets of lug holes drilled... usually 5-100 and 5-114.3, or sometimes, 5-100 and 4-100

so, just a couple different bolt patterns on the same wheel - not a truly universal setup, but moreso obviously than a wheel that only has one bolt pattern...

 

Oooh okay gotcha. Thanks.

 

Would adding a set of quality 114.3 to 120.65 adaptor be a good idea? I own a set of my dream rims (ssr keonig) that I like to install but i dont know if its worth it to take the risk of damaging the car in the long run.
