Best tyre size?? - Page 2 - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

I understand where you coming from Ru,you actualey sound very factual and intelligent there

not that you not

so a 275 does not necassarily give more grip than a 265 because the amount of rubber in contact with the road surface could be the same? Thats me reading it through in my grey matter

The 275 there for would not necassarily put more undue stress on components then? And you would seee a more pleasing fat piece of rubber to the eye

ru' · 17th August 2008, 12:06 PM

I'd guess that the extra stress on 275s compared to 265s would be minimal. Having said that different makes of the same size have different tread widths; I think toyo t1r like I have are relatively 'narrow' compared to some. Did I mention 275s look cool?

dazman · 17th August 2008, 12:15 PM

You just confusing me now

yes you did mention they look cool

thats a nice shiney car you have there sir

looks similar to mine but with shed loads more shine

mine is gunmetal grey but looks black in certain light.Will get a pic up when i get me LMGT4s on

and maybe those 275 fat rubber thingys

255x40x18, wide with some wall, mine gripped fine.

dazman · 17th August 2008, 12:25 PM

I have 245s on at moment they were fine till i upt bhp,they are ok now really apart from that damd annoying twitch out when the power is applied ;-)

Hi
I've just got an R33 GTR with 255 40s,- anyone got any idea what the pressures should be?

Light-R · 18th August 2008, 06:14 PM

hi pete.

i believe that you mean on 18's.

i cant really give you an expert advice, as i am still playing with my pressures.

on the road i use 2.1 bar fronts and 2.0 bar back (my rear cockpit is stripped)
on track i use 2.0 bar front and around 1.8/1.9 back.
both pressures on road tyres.

i really dont know how much pressure to use on the slicks now.
any advices would be appreciated
=)

Pete G · 18th August 2008, 09:27 PM

They are 17 s, but that wouldn't affect the pressures.
I have 35 psi rear, 40 psi front, realy rock hard.
2.0 bar is only 32psi ??

ru' · 19th August 2008, 07:19 AM

fwiw I run 34 front, 32 rear (psi, obviously lol)

dazman · 19th August 2008, 12:49 PM

By the way not to hijack the thread or out

ive ordered 275s x 35s

Light-R · 19th August 2008, 01:22 PM

they do look mean....

275 35's good choice, at 275 35 on 18 you will maintain the OEM rolling radius. Plus theyll look fat as a mother! and yeh, diff manufacturers contact patches have different widths and yeh sometimes the wider the tyre, the less traction in severe conditions.

dazman · 19th August 2008, 02:40 PM

Thanks,just got find a set of these wheel nuts to fit me LMGT4S now,then i can get them on,oh the pain of waiting......

ru' · 19th August 2008, 03:45 PM

Be sure to post piccies when it's sorted.

dazman · 19th August 2008, 03:51 PM

Will do itching to get them on :-)
