I think Tire Rack's program only gives you a "Yes/No" as to whether something will fit. This site gives you all the numbers (how much less space at the top of the wheel well, whether the change in offset will affect the suspension and/or brake system, etc.) so that you can take a ruler out to your rig and see for yourself.

I went to 265/60/18's on 8x18 Borbet rims with -2 offset (stock is +38) which caused the tires to stick out 2" further than stock. By contrast, going to a 285/60/18 on stock rims (as Sue and others have done) causes the tires to stick out only 0.8" further than stock. That difference is why I trimmed a tiny bit more but at a different angle.

I got those numbers from the link I posted above. When you fill out all the info you'll get this analysis back:

Package will stick out 50 mm (2'') farther. Make sure that you have enough room under the fender. If not, consider narrower tires or higher offset. Will fill out the wheelwell by extra 12 mm. Acceptable for most cars.
