Tire size problem at TireRack.com

It's time to retire the Mark. After research I decided to get Goodyear Eagle F1 GS-D3 in 245/50YR-16. When I contacted TireRack they told me that those tires were 25.7" in diameter and would have a negative effect on the ABS system. They would sell them to me but wouldn't take them back if they didn't work. What do you think? I ran Michelin 225/60R-16 on the front and BFG drag radials 255/50R-16 on the rear for a year without ABS problems. I did have to turn off the traction control every time I went out but I could live with that. I really want those tires.

I had 245/50ZR16 on my Mark for almost 18 months without any problems what so ever. Only problem was my speedo was about 3-4Mph off at 60Mph, which kept me out of trouble (never got a speeding ticket in the Mark).

I also didnt have to turn off my trac off, or had any ABS lights come on.

...it's only when you mix sizes that the ABS can give problems.[/div]

On my '93, I've had the Nitto 555R 245/50-16 in the rear with the stock size Michelin Pilots(225/60-16) on the front with no issues whatsoever with the ABS.

This is a link to the whole tire test that convinced me I wanted the Eagles. Below is the section on them.

First Place - Goodyear Eagle F1 GS-D3

As an all-around high-performance tire, you can't beat this Goodyear. It was the best performer in all three wet-track tests and was very competent in the dry. It generated 0.94 g on the dry skidpad, only 0.01 g off the first-place BFGoodrich and tied with the Yokohama and Hankook.

The Goodyear gripped so well that you might not have been certain the road was wet, and it lost traction in a gentle, predictable manner. It held onto the wet track with 0.82 g of stick, an impressive figure considering the worst tire in that test made only 0.67 g.

The Eagle F1 got a lot of favorable comments. In the wet, Geswein called it "direct"—a way of saying the tire provided clear signals about its contact with the pavement.

There were tires that performed better in the dry, but the Eagle wasn't far off. It was a little less precise than the BFG and Yokohama on a dry track, but not by much. And like the Continental, the Goodyear had a high 280 tread-wear grade. At $145 each, it's $34 cheaper than the most expensive tire here.

One thing to keep in mind about the imprints we carefully obtained is that a tire's contact patch changes dramatically as it is loaded, so these prints are not accurate representations of the amount of rubber that each tire puts on the road while cornering or braking.

RE: Tire size problem at TireRack.com

I just went through this last week. I had 255-45-17 Mich Pilots on the front and ended up with some loaner tires while the shop ordered replacement tires for the back. They while swapping the tires from one set of wheels to the other cut the sidewalls on 2 of them. So they stuck me with some Kumho 275-40-17s while I waited. Driving around town was fine. But when I tried to go out of state the ABS went off on me after about 160 miles. When I got back in town and reset everything it was fine again. There's not much difference between these tires either. I just got the replacements put on today and took the car on the highway, everything seemed fine but then I didn't go 160 miles either.
