But why the low profile tires?

If you get bigger wheels with these type of rims then you need 285/40/r22's that is how they fit.

Looks great, Congrats on sweet wheels and Lexus SUV.

Wheels
 

Has anyone discovered a better looking set of rims? But I don't want to go to extreme. Maximum of 20" inch.

Chrome wheels
 

What are people paying for chrome wheels? I've been quoted 1800.00 for perma chrome/ powder coated chrome. This is for 4 wheels, not 5. They keep my wheels to send back for the core charge. This also includes all labor as well...

I've also been quoted 1800.00 for triple chrome from another dealer.

One dealer says the perma chrome is much more durable. I have the triple chrome wheels on my LS 460, but I don't use it in the snow and ice along with all the salt and chemicals on the roads. I've had no problems with chrome rusting, or peeling on any of my cars.

Thanks

I had the triple chrome on my GX470 and after two winters with mag cloride and salt they were badley pitted and pealing. I now have the new GX and am going to stick with the stock wheels.

Thanks, that's why the St. Louis dealer likes the perma chrome. I don't drive my LS 460 in the snow, so I haven't had a problem with the finish...

L.A. Wheel and Tire does it for closer to $750 + refundable deposit (assuming your wheels meet the criteria) on a Chrome Exchange. They've got Winterchrome, which is much more durable than standard chrome; the pricing might be slightly more, but not much.

larger wheels/tires
 

Has anyone used larger wheels/tires to fill in the wheel arch on their 460 that doesn't sacrifice performance and ride?

I read somewhere on this forum about someone putting 285 tires on their stock 18" wheels. Some commented it might be too much width for the stock 18x7" rim to bare weight on.

I had the same feeling on the wheel well spacing in relation to the top of the tire. However, it grew on me as it gives this vehicle more of an off-road look that most crossover SUVs nowadays lack. Wife likes it stock as well. Just my $0.02 but you can check out tirerack.com and they may have some options on alternate tire/wheel combos for the GX.

I put larger tires on... Toyo Open Country A/Ts and love 'em. Look for pics in previous posts.

Wheels size difference
 

Will there be a noticeable difference b/w wheel size of 20x8.5 and 20x9? from original 7.5?

Thinking of getting a new rims.
THX.

-- Added short answer on the bottom :-)

Yes, since the wheels will be wider it will make for a nice looking stand, and it will probably help with handling a bit.

What you have to look for though is the wheel offset and the wheel clearance. With the original wheel on the vehicle measure the clearance from the rim's edge to the shock and any other suspension components on the inside of the wheel well, also measure the clearance from the rim's edge to the fender (on original wheel the tire will probably protrude more than the wheel - but keep in mind that you will be putting on wider wheels). The measurements will tell you how many inches of clearance you have on either side of your OEM rim. Keep in mind that you should always leave at lease 1/2" of clearance.

You always have to examine 3 numbers when looking at new rims: height, width and offset. Offset tells you how much is the hub of the rim offset from the center of the wheel. Zero offset - hub is at the center of wheel. Positive offset - hub is pushed out of the wheel (the wheel sits deeper in the wheel well). Negative offset - hub is recessed in the wheel (the wheel sticks out of the wheel well).

It seems that OEM wheels on the GX460 have an offset of +30mm. So if the new rim is 1" wider (approx 25.4mm) that would add .5" (approx 13mm) to each side of the rim. If clearance measurements permit it, you can get the 20x9 with +30 offset. If you don't have enough clearance on the inside, and you need to push the new rim out more, you will have to reduce the offset by the added inside width (.5" - 13mm), so your offset would have to be +15mm (probably same for 20x9.5 (~19mm each side)). But in this case, the full added width (1") would be pushed out towards the fender, so check clearance there.

Also, some say that wider wheels can adversely affect handling of the car, unless proper offset (for the vehicle in question) is maintained, so do the research before buying new rims. Also, you may need new size tires.

I hope I didn't make it too confusing. :-)

I just did a quick search on tire rack, here's the short answer you were looking for :-)

You probably get worst gas mileage with wider wheels. I think that was one reason why Lexus choose small 7.5. Compared to other vehicles in this class...probably the smallest.

Gsobol thx for the detail answer, but will have to read it couple times to get it.
Suddenly new rims do not look that appealing any more.

So the best choice for a rim is one with zero offset? but if a wheel 20x8.5 has an offset of 12mm and a wheel 20x9 has an offset of 0mm technically 20x9 with 0 offset will be better even though it is wider right?
