Winter rim compatibility ...
 

I have a set of Blizzak WS90 215-55-17 that I wold like to source some basic rims for.

Known: ES 350 lug pattern is 114.3, offset is 30-48, and center bore is 60.1


Found some steel rims that are supposedly for a Mitsubishi Galant, but the specs line up. Lug pattern 114.3, offset 46, center bore 67.1

Hub centric rings to go from 67.1 to 60.1 are about $15. Necessary?

Anything else that would prevent them from working on the ES 350?

while different bore size will install and run ok, I believe hub centric rings are required to avoid balance problems.

Thanks for the link, but I'm just running the stock tire size, which I know fits the rim. Strictly concerned if there is something specific about a 'Mitsubishi' rim that could prevent it from mounting successfully to the ES350, based on the lug spacing, offset, and bore.

If you go this route (67.1 on a 60.1 hub), do get centering rings and do NOT use plastic ones...pay the extra few bucks and get metal rings. The plastic ones can deteriorate and break up due to heating from brakes. I've used aluminum rings with some aftermarket (aluminum) rims for my winter tires and they work just fine with no balance problems at all. In fact, just did the changeout this week. If you don't use centering rings then you are relying on the studs/nuts to center the wheels and that is almost always problematic requiring very, VERY careful tightening of the nuts in a gradual, repeated 1/3/5/2/4 pattern and even then there is no guarantee the wheel will be exactly centered. Be sure that you'll have sufficient brake calliper/wheel clearance as well.

Yes you have to check the lug nut type as well in addition to lug pattern, offset and bore. Worst case you buy also some lug nuts for $25.

I used steel wheels on my Prius from a Volkswagen Jetta. The lug pattern was identical, the offset very close and for the bore I used plastic hub centric rings with no issue for 4 winters. However, I had to buy the exact lug nuts that were matching both the steel wheels and the thread size.

In the case of Lexus and Mitsubishi you are lucky because both they use thread size 12X1.5 Mag seat washer lug nuts. Your Lexus lug nuts should very likely fit the Mitsubishi steel wheels.

Aegean, don’t forget that when braking your Prius most of that energy gets put back into the battery rather than being turned into heat at the rotor/pad interface. That’s the main reason brakes last so much longer on hybrids.
