hey guys im in the process of getting rear tyres at tha moment, i currntly have 225/50/16's on the rear and i have just put new potenza g3's 205/55/16's on the front (front rim is 7" wide)

my rear rim is 16x8" and i was thinking of going 245/45/16's rather then 225/50/16's i know they will fit just bulge slightly but my main concern is that there is a large discrepency between front and rear, what should i do, get 225's or 245's for the rear?

any pro's con's??? i have found a good 245/4516 tyre for the rear toyo proxes t1-s or falken grb fk451, 225's easy to find in any tyre!

thanks guys

no problem with different sizes front to rear except on a GTR, I run 235 front and 265 rear.

but, to me 205 for your fronts sounds very small?

I'd recommend the falken fk451s they are excellent

I have never encountered a problem with different size tyres front and rear on GTR's, or GTS4's for that matter. Width is obviously irrelevant, the ATTESA doesn't know how wide the tyres are. As for diameter, that's a furphy, otherwise you would have to buy 4 new tyres everytime, because the diameter is around 16 mm different (8 mm of tread depth) between a new tyre and a worn out one.

An example;

Say you use a 225/45ZR17 on the front which is 635 mm in diameter when new

While you use a 255/40ZR17 on the rear which is 640 mm in diameter when new

The 5 mm difference is way less than the tread depth, so it would be the same as running new tyres on the front and half worn ones on the rear.

    • Should add all mods on the car are done in my ownership. The car was a 1 owner in Japan and I'm first owner in Aus.
    • Thanks GTSBoy. Did BC's so not Japanese coilovers. I've already done all the other points you mentioned besides the seat, I like the factory seats and want to keep original look. Done all the fluids and comp tests etc and all consistent and clean. Well and truly used to the power and car as I've been driving it for a few years as it is now. Contemplating next steps mainly. Preference to remain twins too. @Murray_Calavera Paying for labour.
    • Hmm. I don't think it is possible. As soon as you start, you will be on the hook for all the money. $5-10k is enough to make it fragile. Here's the list of things you need to do to make it nice, and driveable. If Japanese coilovers, get them measured and tested, then decide if you're keeping them or replacing them. If low rate springs, then consider big ARBs. If high rate springs, then probably leave stock ARBs. Either way, ad decent end links. Replace and/or upgrade all suspension bushes. That's LCAs front and rear, UCAs & traction arms at rear, caster rods at front. I highly recommend GKTech FUCAs, although the step to spherical joints is a step too far for some people. Rebuild brakes front and rear. This means making sure the calipers are healthy, discs are up to thickness, hoses are replaced with braided. Add good pads and fluid. Investigate wheel bearings all the way around, tie rod ends all the way around, upright bearings at the front, balljoints everywhere. Any of these that are still original are likely to be a bit wibbly nowadays. Bride or Recaro driver's seat, with fairly deep sides. Nice tyres. Street performance wheel alignment. Or track focused, if you're not going to use it on the road. Fluids everywhere if not known to be fresh. Now, learn to drive the car as hard as it will go, before trying to add any power. Save up big $$. $5k is the minimum cost for putting a decent ECU into it. A big single, with manifold, new exhaust, injectors, fuel system upgrade, ignition upgrade, triggering upgrade, etc, is >>$10k. None of that (except the ECU) is a good idea on an old RB. You really should put head studs in it, investigate engine health (compression and leak down, real oil pressure at revs, coolant condition, etc) before even considering adding power. There's nothing sadder than the "I added boost then it shat the bed" thread.
