Yea there are a bunch of people running them. They are considered to be the best ST* tire by most. But they cost big bucks (210 or so a piece).

I'm starting to get my car setup for STU. Why doesn't anybody run a 255 tire? It will fit on an 05 STi.

Because 245 is the largest allowed on AWD cars in STU.

I want more tire, though EVO's can fit more rubber than STI's can, so it might not be a good thing to wish for.

Alright, the courses I run are usally about 30sec at one venue and 60sec at another. Give or take 10 seconds. Which one would give me better gearing to stay in second gear, 245/45?

245/45/17 vs 245/40/17... the 45 will give you taller gearing.

Most drivers feel that if you have to shift to third, you might as well do it earlier with the 40 series tires ... plus you get a stiffer side wall and lowering.

I think I might stick with the 45 series, not shifting 3rd and then later back to 2nd is one less thing to concentrate on. I loved my Civic Si that thing never ran out of 2nd even with 205/40/15s.

like mako said- there's a good chance you're gonna need 3rd anyway depending on the course. especially in MA, you're probably running at devens.

The 245/45/17 tire isn't going to get you that much more speed in 2nd gear, but it can be helpful on tigther courses.

The first three gears in an '04-'06 STi are:

1st--3.636
2nd--2.375
3rd--1.761

I know redline is 7,000rpms and I think fuel cut occurs at 7,100rpms (someone please correct me if I'm wrong). Using 245/40/17 tires, max speed in each gear: 1st = 37mph, 2nd = 56mph, 3rd = 76mph. Using 245/45/17 tires, max speed in each gear: 1st = 38mph, 2nd = 59mph, 3rd = 79mph.

Food for thought...

Yup, you WILL end up having to shift to 3rd ... if you just ride the rev limiter in 2nd, you will end up holding yourself back eventually. When you get engine managment you can also increase your rev limiter +500 ... which in the low gears, for short bursts is not considered harmful.

If the rev limit is increased to 7,600rpms, using 245/45/17 tires:

1st = 41mph
2nd = 63mph
3rd = 85mph

That's almost perfect right there - as speeds on an SCCA legal course, should not exceed 65mph for *SP cars.
