Pilot Sport 4S tires on a GT350

[earlSpilner]

Hi all I am looking to replace my soon to be done Pilot super sport tire with the Sport 4S tires. My question is if the slight difference in tire size will affect my speedo or ABS?

There seems to be no direct replacement size for the GT350 (non R) in the PS4S tire.
fronts: 295/35ZR19 (same as stock size) or 295/30ZR19
back: 305/30ZR19 or 325/30ZR19 (note there is no 305/35ZR19 size in PS4S)

Has anyone used these tires on there car? Do you like it? My attraction to the PS4S over the regular PSS is the tread life.

It'll have a nominal change to your speedo. The stock tires are 27.1" for the fronts and 27.4 for the rears, your new p4s specs are 26" and 26.7". Your speedo will be off by a few miles an hour, but your abs shouldn't be affected. If you want to match your existing rolling diameter, there are 285/35/19 and 295/35/19 in the p4s, but I would go with the tire sizing that you picked and ignore the speedo differences.

Earl- how many miles did you get out of yours. I’m at a little over 12,000 miles and going in tomorrow for a new set....

mich is not making pss anymore, the 4s is its replacement. i run 4s, 305/30 front, 325/30 rear with r-spec rims and have no complaints. others run 305 or 325 square, either way ur speedo will be off. look at the sticky on re-calibrating ur speedo its real easy.

More so than the speedo is your ground clearance will be way less....

I like the 295/305 sizing for the GT350R and especially GT350 wheel widths over the 305/325 sizing. Although for GT350 width wheels, I would stick with the bespoke PSS tires.

Don't know if it's a sticky or not but it should get you what you're looking for.

Just go with a square ps4s 305/30 setup on the stock wheels. Fits, and works. Just did that 1000 miles ago

+1, I did square 305/30-19 PSS on my SV501s in stock R dimensions. does indeed work well, and both front and rear wheels sizes are in the acceptable width range for that tire size.

Having an R, this came extremely close to factory rolling diameter also; for non-R folks you'll get a very slight gearing advantage from the shorter tires.

I get about 23,000km out of mine with a couple of track days. I now have a set of NT01 track tires for track duty so these will be purely for street use.

I found this tire size comparison tool which I am also finding helpful: http://tire-size-conversion.com/tire-size-comparison/

For street driving this seems like a good idea because i could rotate the tires front to rear (still need to mount dismount) to get a little more life out of them. Currently I find I am using up the fronts faster than the rears.

Plus with 305 in the front I only loose about 1cm of clearance vs 2cm for the 295.

Am I understanding correctly that 305's on all 4 corners will work with the stock GT350 front wheels?
