Wheel Sizes & Offsets For Skylines


Recommended Posts

Thinking of ordering myself two front rims to start of with for my r33 gtst and i am going to get rota grid r wheels. I saw another gtst running 18x9.5 +20 front. I forgot to check the inside of the guard but would this be a perfect fit and not scrub the inside lip? Was a pretty neat fit and am pretty sold on that fitment. Who runs this fitment?

it was on 225/45 rubber and nice stretch

Can anyone give me advice on tyres to fit my 10" XD9's.

Was originally gonna go 255/35/18 but it will result in a sidewall that is a bit narrower than I'd really like, and a smaller circumference than the stock wheels. Plus more $$$$.

Now thinking either 245/40R18 or 235/40R18.

Advice on those two sizes?

you don't note the car it is going on. If it is a GTR (which im assuming as that is a GTR fitment wheel) then why not get some 285's (35/18) on there?

yeah they do look good but that will rub on a gtst. how much depends on tyre size and camber etc.

what offset do you think would be good with say just standard camber and suspension, then what do you think would be the correct offset once running coilovers and playing with camber and having it set up for drift?

R33 Gts-t. More concerned about the rolling diameter (speedo accuracy) than anything. I've got 235 on at the moment and they give good traction. I'm not skimping on tyre quality.

ah, then fitment and the issues with a wheel that size on a gtst is up to you.

meh, there is nothing in it and speedos are designed to over-read the speed.

If in doubt either get the speedo adjusted or just go through/ drive with a calibrated speed sensor to work out how far off your speedo is from true speed.

you do realise that profile isn't actually a mm measurement but a percentage of the width don't you?

the difference will be less than 5mm in height between all sizes you mentioned

he isn't putting on 10 -45 or some hellaflush craze, they are +38's or something.

I thought they were around the +20 mark...?

regardless, 10" is pretty big for the front of a gtst and will need some thought work and appropriate tyre sizing.

LOL yes I know, I'm just not sure if that 5mm extra sidewall each side will make a big difference to the stretch/appearance of the tyre once mounted.

They're +38 and they're going on the back, got 9's going on the front.

well as they are ~4mm higher and 20mm wider they are definately going to look less stretched than the 235/40's

    • Updating results.  Using ATR45SS-0 model VS UHF57-900. Those two are very different turbos, different wheels sets with different wheel hub profiles but yet with almost identical result. I’m intrigued with both turbos performance. ATR45SS-0 was a 61mm turbo first developed in May 2020, UHF57-900 was a 62mm turbo developed in March 2024 as a powered up alternative of a G30-900. On paper ATR45SS-0 maxed at 563rwkws, while UHF57-900 maxed at 568rwkws. ATR45SS was slightly more responsive with slightly better power band through the mid range.  Road driving ability, ATR45SS-0 had better throttle response, felt more robust under throttle, as it wakes up earlier. I think G series wheel hub design made it to have higher inertia under light throttle. Doing bit more prototype work in the next few weeks, will update result when its back on dyno again. ATR45SS0 Blue, UHF57-900 Red Chequered tuner's Dynapack hub dyno, E85 fuel. Mod list is in video below video_20240604_114214.mp4    
    • Did you run the power cables for the mac valve to the other side of the car near the fusebox? Utilizing the stock boost controller cables? or did you run new ones?
    • Hey I have a potentially stupid HICAS question 🤣 I'm currently doing a full hicas delete, Power steering pump modified to non hicas, all lines removed from the car along with all electronics. My stupid question is - Do I need a lock out bar? is there any reason why I cant just remove everything from the rear end? I already have a lock out bar but thinking to save a few extra grams I could also get rid of the arms and tie rods as well and just run it with nothing in its place? or would it have a negative effect on handling?
