02 SS Tire Combo Question

[SS#337]

I am thinking about one of the following combos with the Goodyear F1's:

245/40ZR17 in front and 275/40ZR17 in rear
or
245/40ZR17 in front and 285/40ZR17 in rear
or
255/40ZR17 in front and 285/40ZR17 in rear

Any thoughts?

Why the 245 or 255 up front? The stock SS tire size is 275/40/17. The 285s would be good for the back though.

[SS#337]

I was thinking of a more bold muscle car stance. I guess it is the rear that gives it that look anyways huh. I had also thought about leaving the front stock tires on as fourth option. would there be nay handling issues with the wider tires on back? Any other thoughts are greatly appreciated. Thanks.

I would stay with the 275/40s up front and go to 285/40s in the back like you mentioned. You are correct about the rears giving it the bold muscle car stance as well. No handling issues with 285s, you would be perfectly fine!

Great. Thanks for your input!

Great. Thanks for your input!

Glad to help, post pics when you get them mounted

[SS#337]

will do.

if you want a skinny/fatty look, then go 245/45-17 and 315/35-17. the sizes you are looking to get are different height and will kick off the ABS system.

Semi confused here, how will the different heights kick off the ABS and I didn't think it was safe to put 315s on a 9.5" wide wheel?


Thanks for explaining further

[mrr23]

245/40-17 = 24.7" tall
315/35-17 = 25.7" tall

with the front tire being shorter. it will spin quicker than the rears. the computer picks this variance up as the front tires skidding. so, the ABS system activates. the ABS and brake light will come on the dash. when you go to apply the brakes, the ABS system starts pulsing the brakes because it thinks the front tires are skidding.

as far as 315/35-17 being not safe to put on 9.5" wheels, don't believe that post on ls1tech. i rode around on 315/35-17 nittor DRs on my 17x9.5" wheels for a year. hell, at one point, i had 335/35-17 tires on them. that was pushing it.

Thanks for the thorough explanation, that helps a lot. I don't believe much from tech for the record either. Just full of a lot of egos over there

IMO i would go with a 275/40/17 all the way around. i miss not being able to rotate my tires. Also i would look into a Kumho or maybe a yoko tire. i wasnt too pleased with my F1's

[SS#337]

I have the SLP chrome 10 spoke rims so you say I can go up to 315 without having to buy bigger rims for the rear? I thought I would have to go to an 18" to fit the 315s. I am looking to keep the rims I have now, just get the "fatty" look in the back.

[mrr23]

on a 9"wide wheel, depending on brand of tire, it will distort the tread pattern by being a bit on the narrow side for a 315. i have seen people with 315 on 17 x 9 wheels. there is a point is diminishing returns.

[SS#337]

which means what exaclty...what will be diminished - just the tread wear? I am new to this arena...just trying to understand what will work here. I just want to get that fat stance in the rear without going to a bigger rim or meesing up anything ie ABS (thanks for that info). So what would be my best combo? Don't really care about rotating tires that much at this point. Oh and this is a daily driver - if that matters. - Thanks.

[mrr23]

when the tire gets too wide for the rim, it will distort the tire. this can cause handling issues. what happens is when the TREAD width of the tire exceeds the rim width, it will curve the tread.

for you with your stock wheels i would do this

245/45-17 front
275/40-17 rear

both are 25.7" tall and don't affect the braking system.

[SS#337]

ok, sounds good. Thank again!

btw I was thinking about the Nitto's/NT 555 EP or the BFG's/g-Force KDW, whatcha' think?

[mrr23]

KDW are good tires. haven't read up on the EP.

[SS#337]

ok. thanks.

[Y2KPewterSS]

Another vote for KD and KDW tires, EXCELLENT
