So...I am planning on purchasing wheels next week, and am stuck in a bit of a dilemna.

I am buying a set of HP Design Evo's in 19x8.5/19x9.5 fitment (for a sedan).

I am having a hard time deciding between the following tire combos, and after a search have seen various opinions.

Tire Combo #1 ----------------------- Tire Combo #2
245/40/19 F ------------------------- 245/35/19 F
275/35/19 R ------------------------- 275/30/19 R

I will be purchasing the BF Goodrich KDW2 tires in either of these fitments.

By using a wheel calculator, it shows that tire combo #1 is closer to OEM spec. However, I am switching out my springs for Tein Basic coilovers, and expect about a 2" drop all around. Tire combo #2 is less likely to rub, but I am worried that there won't be quite enough tire, and the ride will be unnecessarily harsh.

Your thoughts/experience with either of these setups will be greatly appreciated.

Thanks!

I would go with combo #1. The closer to overall stock height the better and the extra sidewall will give you a little more piece of mind.

If you have the right offsets for your wheels, you will not have to worry about rubbing. What offsets are you going with?

With these wheels, my only choice is 38 front and rear. I PM'd illg35 who had this combo before on his sedan, and he went with combo #2 and said that it did not rub at all. I am worried that with the extreme drop I will have, combo #1 may rub...

You will be better off with the tire combo number two. The other will be too tall for the sedan.

Another point to consider is that these HP Evos only come in +38 offset in the 8.5" and 9.5" rims. You will be just fine in the front but ideally in the rear you want to have a +45 offset with that size rim.

So be aware you will likely have to roll or cut your rear inner fender lips to accomodate properly.

BTW, the ride quality will be close to OEM with the proper tire pressure. I recommend around 37psi in that tire size.

I am prepared to do so, but there may be a chance that I can escape, provided I can get my negative camber between -1.5 to -1.9 and neutralize the toe.

Why not go with 245/35 for the fronts and 275/35 for the rears. Here's what I calculated:

Wheel Diameter: 19 19 19 19 19
Tire Width: 225 245 245 275 275
Aspect ratio: 40 40 35 35 30
Overall Dia.: 26.087 26.717 25.752 26.579 25.496

Going with 245/40F and 275/35R would make the overall diameter difference of almost 1.2". That might pose a problem with the VDC especially since it's the fronts that are taller. The 245/35F and 275/30R poses the same issue. But with 245/35F and 275/35 rears, the overall diameter differs from factory by no more than .3" and since the rears are just .7" taller than the rear, it is as close to factory as possible.

In that case go with combo #2 and be prepared to cut or roll your fender in the rear as Chico pointed out.

Have you thought about the Dunlop Direzza tire. The side wall curves over giving you a bit more clearance. check it on my sedan

Not a fan of Dunlops.

The only other tire I will settle for is the Toyo T1R.

High-end Dunlops are the ****...not those Direzzas though. Have you checked the wheel/tire calculator to see which one keeps you in spec?

and you base this opinion on what criteria?

I have HP hr5 wheels 245/35/19 8.5 front & 275/30/9.5 in rear on my sedan lowered with 350z springs, and yes they only come in +38 front & rear
front is perfect but rears is real close to fender so i had them drilled out
milled to +43 and inserts installed perfect no rubbing no problems with alignment cost about $100 to have wheels done the right way way cheaper than ordering custom wheels .

Sorry, I was thinking you had a coupe, but you have a sedan. Well, in that case, I'd go combo #2 if you're planning on dropping the car.

Quick update. May be going with wheels that have a +35 front offset, and +40 rear. I am still going to encounter the same problems with the rear fender?

Yes, but not as bad.
