I'm looking for conformation that a 2008 GL550 wheels will fit on a 2008 R350?

What size rims are the gl550. Bolt patern should be fine. It's the offset. Lots of posts on here about what offset works and what are the limits.

Agreed. Offset will likely be your only issue.

Post the specs of the wheels and include tire size.

All I know at this point is seller say they Fit GL 550 and 450 2008 and up. Tires are 295/40/21

I would say that you are likely good. GL rims tend to have a higher offset than R rims, so you may need spacers and longer wheel bolts to get the right look. Higher offsets cause the rims to fit deeper in the wheel well. It is measured from the centre line of the rim, so often as rim width is increased so is the offset to maintain alignment with the outside of the fender.

Thanks. I found the set and mounted Continental tires for $800. What do you think? Tires have over 50% life left in them.
Where can I find the spacers and longer bolts?

marc hanna

That's not a bad price. Are the rims in good condition?

You can buy spacers and bolts lots of places. Make sure they're hub centric.
Ebay, local performance/wheel shop, etc

Haven't laid my eyes on them just yet. I've only seen pictures. Seller says they are in great shape.

If you are picking them up anyway, make the purchase pending fitment. If they stick out too far, (like -33 offset), they will rub and then there is no fix for that. 295 width is a very wide tire. May look good but ride will suffer. If it all fits, then post a pic please.

That's good advice. The low profile will be a rougher ride than the existing tires - some people notice it more than others.

Thanks. I may just keep it stock but you guys with your larger wheels really makes me want to change.

I asked for specs and he sent me what was stamped on the wheels.

I have no idea what all this means?

That's a 21" diameter x 10" width x 37mm offset

marc hanna

Mine are an 8.5" width with 32mm offset, and they look like this:




Yours would stick out from the fender about 5/8" more than mine.

Here's a few more shots to give you an idea. I really like my offset, but for you to get this fitment you would need an offset of about 50mm on a 10" wide rim.

Thanks for the help!
