I planning on replacing my 265/40R20 104H tires on 2015 audi A8L.

I found good deal on Goodyear EagleŽ Sport All-Season (265/40R20 104H) around $200 per tire + $19.00 installation fee

this my first time replacing tires and i wanted to get your guys advise on whether this option is a good idea or not. i don't really care for the most expensive tires

You might want to look at the 275 width tires too, lots of options there. 265 are kind of an orphan size that only a select few vehicles use per OEM. The difference is width/height is usually not an issue at all...

Yep, look at 275/40's--unless it is a lease car where you probably need to stay strictly stock on tires. A lot more selection, many V or higher rated without paying big bucks. 11 choices in 265's become 71 choices on TireRack's site, including a W rated version of what seems like the Goodyear you were considering, at a similar $205 each.

Fits fine, and if anything speedometer reading will probably be more accurate. A common worry FWIW--check your 265's now with a GPS app and it will probably be a little optimistic, which the next minor size larger will help clean up as a dividend.
