New Tires

[2.3Lxhatch311]

Installed some Fusion IR 195 50 15's today. Great tires. Car accelerates more quickly, handles better, and can even reach a higher top speed (in a respectable time) I'd reccomend these tires to anyone who likes lo pro's. My price, 200. Retail, 289. They have a directional and very agressive tread, and the side wall's are super thick. They seem like you could run em flat without hurting ur rim.

what size tire did you replace?

 

[2.3Lxhatch311]

225 70 15 (truck tire)

so the tires you have are a lot smaller diameter than what you had. This would explain the acceleration feeling.
The car may be a tad (maybe) quicker, but it would look faster as the speedo is probably off a bit.

It's a little more than a Tad, the Big thick truck tires reaaaaly bogged it down before.

Well, I cracked my exhaust in a driveway today. So much for performance... gotta watch the low clearance.

Yea mine rubs sometimes, I need to get it off and fix that, but that probably won't happen until late May when I get home from school.

I debate the higher top speed part....
obviously acceleration would be improved with the smaller tires due less rotating mass. Not to mention it takes more effort to move weight that is further out. But the bigger tires did mean a potentially higher top speed. Other than that Fuzions arent bad tires. Not great. But defintely good.

But anyway that smaller tire is just simply spinning faster while the larger one spun slowler.

With the 225/70/15's on your speedometer was -6.4 mph off at 60 meaning you were doing 66.4
With the 195/50/15's on your speedometer was +5 mph off meaning at 60 mph you are doing 55mph.

This is assuming your car has the correct gear for the speedometer and tire size and such.

Just fyi for you.....

Ill stick with my 225/60/16 z rated firestones
sure they rub alitle when i turn hard with some one in the pasinger seat but i can live with it. the car turns like a bat out of hell!

My reasoning for the higher top speed thing is; Even thought the larger tires gave a higer 'theoretical' top speed, the engine could not produce enough power to effectively reach that speed. By reducing the true final drive ratio, the engine is able to push more wieght with less effort. There fore, even though it can't reach the same theoretical top speed, It can reach a higher real life top speed. I hope that makes sense. Dunno how bad off the speedo is but the other night I had it tapping the reset for the (can't remember real name) little odometer.

I see your reasoning... But since you made such a large jump in tire size. from one real far off tire size to basically another its hard to say. But I will say this. Your most likely not any faster than a stock tired car. My 89 Coupe came with 195/70/14's it now has 215/60/15's on it. Felt no difference at all except she is more stable higher up and while cornering.
