WIdest tire on stock 18's
What is the widest tire anyone has put on the stock 18" rims. According to Big Custom Wheels website, it shows that a 285/40/18 will fit a 18x8.5 wheel. Is this correct? Has anyone tried this? A 285 seems a bit wide for a 8.5 wheel to me, but it would be nice if it would fit.

Test on this page:

You'll see that with 285 tire you need a 9.5 to 11" rim width

Her is a link that I saw the recommended tire size on. The site is Big Custom Wheels. They recommend a 8.5 to 10.5 for a 285/40/18. Is this incorrect?

Check www.TireRack.com
They have great information on there, and it agrees with 1010Tires on the 18x8.5" wheels.

Just make sure you maintain the overall diameter(27.3") when making tire width changes.It could throw off your speedo a bit or a lot.Here is a tire spec sheet from BF Goodrich for reference.Tire manufactuers differ in sizing but not that much.

Big Customs specs don't agree with the tire manufacturers specs, lawsuit waiting to happen?
Example: From Goodyear's website
275/40ZR18 Approved Rim Width 9.0 - 11.0
From Big Customs on the same Goodyear tire.
275/40ZR18 18x8.5 to 18x10.5
Sure it will fit, but its not approved and not the the best for handling.
Even tho I am planning on going this route possibly, lol. But I will test mount a tire 1st.
Why would they want more sidewall flex? That's whats going to happen.
