Show me your 285’s on 11” wheels

[ModularKid21]

I’ve been researching for longer than I care to admit, but I’ve decided on running either 285/35 or 295/35 on a set of 11” wheels. I don’t care for the look of a 26” tall tire (305/30) and I suppose I could run a 305/35 but there aren’t many tire choices in that size. Hence why I’ve narrowed it down to the aforementioned sizes. There are more options in the 285/35, and they’re cheaper. The 295’s would fit a little better but there are less options and they’re more than “slightly” more expensive than the 285’s. I’ve seen a couple of guys with 285’s on 11” wheels, and I’m leaning towards doing so as well, but I’m wondering how many others have ventured down that path

So the pics with the tape measure are a worn down 285/35R19 RE71R and a new just mounted 305/30R19. Basically the same height. A newer 285/35 would be slightly taller due to unworn tread blocks.

You can also see what a very abused 285 (which spent most of it’s life at the limit on a 9-9.5” wheel and has extra worn shoulders) looks like versus the more square sidewall on a 305 tire.

That’s interesting. I understand that not all tires are created equal, but a 285/35/19 should be somewhere near 27” tall. Do you think the decrease in height is due to the 285 being stretched onto an 11”? Even at a full 8/32 tread (advertised re71r tread depth) that 285 would only be a hair over 26” tall. Do those tires run small height wise? I guess I just thought a 285/35 would be taller without question

I measured a 295/35 MPSS on a gt350 19x10.5 and it came out to 27” exactly. Tread depth was about 6.5/32

Well 285/35 is shorter than a 295/35. (35% of 285 is less than 35% of 295). The 285/35R19 RE71R lists at 26.8 diameter, and yes you might loose a tenth or two when stretched. Then subtract twice the tread depth and it adds up within the tolerance for error.

to be fair, I do see a little more gap to the fender with 305/30 RE71s on 11s versus my street 285/35 MP4S on 10” wheels, but the wideness of the tires looks better than 285s on the same wheel IMHO, and I’d rather have wide mean tires than marginally less wheel gap, since my car is lowered 3/4” anyway. My eye is drawn to the meat on the tire, not the air between the fender and tire.

Yeah. I mean with tires, where it’s anything goes at the manufactures discretion, I try not to look too far at the numbers and calculations because there’s always tolerance for error. I just assumed that with 285/35’s being almost 27” and 305/30’s because almost 26”, the difference would be more apparent.

I’m with you on the functionality for the most part. My car is primarily a street car so I’m looking for grip, but I’d be a liar if I said that wheel gap/looks had no impact on my decision. Someone on here once told me “Achieve function, form will follow.” That may end up applying more here than I originally intended.

You’re still on Steeda DR’s right? Have any pictures of your car with the 285’s and 305’s on the 11” wheels?

 

[NightmareMoon]

Here’s a few more. 285 MP4S (on 10s) vs 305 on 11” wheels. I would run 11”/305 on the street too if I had to do it again, but its overkill, no doubt.

I’ll probably end up going with some 285’s. A little more wheel gap wouldn’t necessarily be a bad thing as these wheels will poke some, and I’m lowered a little more than an inch up front. Thanks for the pics/info

Keep in mind that a 1" shorter tire diameter only increases the tire to fender gap by half an inch. The other half inch goes to lowering the car.

285/35 on 11" wide wheels in my sig pic. 18" vs 19", but you get the idea.

@Norm Peterson … does the 285/35 on the 11" looks streched? Everywhere i have read recommends the 305. Please advise as i will be buying tires tomorrow. By the way no track neither lowered in my case.

Thanks in advance..

Best picture I have handy. MPSS tires come with a rub strip down near the wheel's flange.

I really can't comment on what might "look stretched" to you because subjective opinions concerning tire appearance vary and I know that my own preference runs to fitting tires on wheels that are wider than "measuring width".

You should probably use a tire size's "measuring width wheel" as your basis for stretched or squeezed/pinched, which makes a 285/35 mildly stretched on either 10.5" or 11" wide wheels (10" is measuring for that size, 11" is max recommended).

There's nothing particularly sacred about running on "measuring width" wheels, either. All that width really is, is the wheel width on which a tire's tabulated measurements are made. Many OE fitments do use "measuring width" partly as a decent overall compromise between ride quality and handling.

Ended up going with 285/35 Indy 500’s

Do you have any pics with these mounted on the car? These look meaty!

Just a quick teaser a took a couple weeks ago. I just threw them on to check fitment. I had just taken it off the lift and rolled it off the wood blocks so the ride height looks a little high. I’ll be sure to get some more when they go back on

Thanks. It's a close fit. Be sure to post pics once she's all done.
