R 33 Gtr Tyre Sizes.

[Tonkachow]

I am buying 4 new tyres and have 18' rims. Can someone tell me what is the biggest tyre I can go all round on a 33 gtr please.I have standard suspension.I am confused by some things the tyre places have told me about going bigger on the rear etc, despite me telline.

cheers

What size are your rims?

18x9/9.5/10/10.5?

I wont be able to help much, but just more info for others to help.

Offset?

Then it should be a breeze.

yeah man whats the offset ????????????????????????????????????????????????

[blind_elk]

Offset has no bearing on the size of the tyres. Only thing to consider is the width of the rim. Once you know that, check the manufacturer's spec sheet to determine the optimum tyre size to fit.

[Tonkachow]

sorry I thought I corrected my post, but it seems I have posted a whole new post again. The rims are 18x9 all round. The tyre shops I went to told me I could go bigger on the back 275 and smaller on the front 235 and apparently with those tyres they still have the sam rolling diameter, HOW I have no idea.

Cheers.

Why on a GTR?

Legality on a 9" = 235 Min, 265 Max I believe.

I wouldn't run staggered widths on a 33GTR...

[Tonkachow]

Ok point noted and taken on board. I dunno why on a GTR, they were just carrying on about staggered setup. I will just stick with 245 all round then.

Cheers Again.

what the hell , offset is important if you want the tyres stretched or inside the guards depending on what you want , if you say stock offset at least it gives a clue as to what you can fit .

jesus, what an abortion of a thread...

what are the sizes and offsets of your rims...

offset is needed as if you have say an 18x9+0 you would need smaller tyres than say an 18x9+30

245's sit nicely on a 9" rim, but remember that 235's are much cheaper in all tyres as they are a MUCH more common size and are only 10mm less contact area

if your car isn't insanely modifyed then 235 all round is fine for traction

[Tonkachow]

I wouldnt put my house on it but I think the offset of the rims was +20, does that sound right??

Never seen 235s on 9s but the 285s I have on my 9.5s fits perfectly with no stretching at all. However, I have another friend with 265s on 10s and they look a bit stretched. I was told 265s would be the perfect size for 9s though.

Sounds alright. Typical GTR offsets are from +12 to +22

18x9.5 - 265's all round.

No idea why tyre shop would think you require a staggered fitment.

Wouldn't 235s be slightly stretched on a 9"?

btw, rolling diameter can still be the same with different width size.

Don't go staggered on a 4wd car. The altessa system is designed for the same front and back. for 9in rims between 235-265 is legal as said above. Up to you. 245's sit best I reckon.

Also with +20 9in rims on a 33 GTR they will fit fine. No need to take offset into account because they are a very safe offset.

[joeyjoejoejuniorshabadoo]

imho 235 is better on a 9" as they are a fair whack cheaper and realistically there is fuck all traction loss between the two sizes.

having said this i do run 235 front and 245 rear but i'm on 9.5" anyway

[Tonkachow]

Thanks for that Richo makes me glad of the decision I made, I forwarded that link to the guy at the tyre place, he found it interesting and was glad we didnt go staggered either, now he knows not to recommend it to anyone with GTR's

Got 245's put on all round, thanks for the help peeps, appreciate it. Now to the rotors and brakes to get replaced.

What a load of crock! You shouldn't be stretching tyres on rims. Tyres are designed, from a performance and SAFETY perspective, to suit a particular width rim, irrespective of the offset of the rim. The total wheel width & offset and tyre size package should be assembled with the optimum of performance and safety in mind. If a particular wheel / tyre combo won't fit under the guards, then something is wrong.

And legally (roadworthy-wise) the rim / tyre MUST fit inside the guard, ie no part of the rim / tyre can protrude beyond the line of the bodywork..
