the goodyear eagle F1 GS-D3 comes in a 245/35/17 I just need to find some good and cheap wheels that I can run a 17x8 in the back and a 17x7 or 16x7 in the front of the same design so I can do 245's in the back and 215-225 in the front

Here's a link to the wheels I'm using. Kodiakracingwheels.com  Expensive, not real stylish, but they do make custom widths and offsets... and in the wider sizes they will save 10# or more per wheel. Better handling.  Better acceleration... and it's like bolting on an extra 10 HP.

Your MSM makes 240 rwh... divide this into the car's weight and you get roughly 10#/hp.

Saving 40# weight for a set of wheels= 4 hp equivelant (static)... then multiply by an approx 2-4 times correction factor (for dynamic)=  8-16hp equivelant.

It might not be what you're wanting to hear, but that's likely too wide a tire for the HP potential of an MSM.  You'll likely loose more in drag/resistance than you'd gain. 

The combo of an overly wide tire and a "cheap" (heavy) wheel might just make you slower than before. 

You've spent so much in getting your extra ponies... I'd hate to see you go backwards.

Get some Volks! TE37s in 17x8 are probably like 15lbs. But not cheap, but either are the Goodyears I'd guess.

BTW, won't a staggered setup mess with the ABS? Or is the 245 search/find related to trying to find a tire that is wider for back that has the same rolling diameter as a narrower front?

The 245/35 is only .3 taller than the OEM tie and the 215/40 is the same so that combination might work fine.

I spend all my time driving with the abs disabled anyway. the purpose of the 245 in back would be to handle future power levels of over 300whp. in that event even losing 15whp due to drag from the larger tires would be a fine trade

So how would this affect the handling dynamics of the car should you put on 215/40's front and 245/35's on the rear?

Those looks great, hard to beat that price and weight. Too bad the gunmetal has the polished lip, but some people love that. The 16" doesn't have the weight listed (having evil toughts, I'd like a set of 16s for street and other fort autoX/track).

You still might not need the extra width.  I'm able to hook up just fine in my 500rwh/520rwt roadracing corvette... and I'm using DOT Hoosiers just a little larger than what you're thinking of putting on your mazda.  (245X17f/275x17r for rains; 275x17f/315x17r for dry)

When I ran my spec miata, you could really notice the impact of your tire resistance, in fact there were some corners that you would essentially "turn-in to brake"... the srubbing of the tires would slow the car enough to get you to the apex of the corner.

Have you ever thought of using a stickier tire, rather than a wider tire?

I'd think the wider tire might give a lot of understeer when not under a lot of power. I guess not that big a deal, just add throttle to give more oversteer!  reddevil
