Default Sidewalls/Contact patch on Kumho 712's

I think everyone here can agree that size for size the Kumhos for some reason tend to have more rounded sidewalls and therefore a smaller contact patch than the next tire. Well I'm looking for tires for my 16x7 rims and am kinda thinking a little cooky...

Here's an exerpt from a thread comparing Azenis to Kumhos... http://forums.clubsi.com/showflat.ph...b=5&o=0&fpart=
----------------


The kumho 712s only give approx 6-3/4" of a contact patch due to their rolled sholder design. Compare that the the Azenis pic bellow.


Now look at the same size 205/50 Azenis contact patch!! 7-1/2" wide contact patch!! That's an extra 3/4" of rubber on the road for the same size tire. You can also see that the shoulder is more squared off to the side wall then the 712s are.

---------- end

So what I'm thinking is 215/40-16's are going to be too small in diameter, so next best bet would be 225/40-16's. IMO these should equate to the average 215/45-16. Do you guys think it'll rub or its overkill, or judging by my "exerpt" it might make sense? TIA

i think both are good tires, and both have pros and cons...

the kumhos will last longer, but the azenis will give better grip. if u plan on road racing, then go with the flakens.. but for their costs, u cant go wrong either way.

You won't be able to fit 225's under the fenders w/o some extensive body mods.

I agree that the average 225 will not fit, but given my argument and evidence from that other thread, you don't think its a possiblility?

I think 215's will also rub unless you roll the fender arches.

Honestly, for daily driving, no track events, how many miles can you get out of the azenis? Is 10-15K with track events or not?

I forgot to mention they'd be on a 16x7 40mm offset rim on a DA.
