Hi folks
would 16” steel snow tire rims fit GS350 awds ? Any clearance issue with our large front calipers?

 

I have the 17'' rims from the gs300 on my 450h as winter wheels (225/50/17 tires) and it barely clears the calipers. GS350 (rwd, hopefully awd too) has the same calipers and discs (at least up front), to my knowledge. From what I've gathered, 17 seems to be the lowest you can go, up front at least.
You might want to look up the internal profile of the rims you're looking at beforehand as well - I've seen reports of 17s with otherwise identical markings not fitting (or maybe the internal profile markings were different? forgot).

 

If it were a 2006 GS300 yes, but you say its a GS350 with the bigger caliper so no on the 16" fitment.

Look on craigslist for a cheap set of older 17" is250 wheels. They can be had for cheap
