are you referring to this thread?

http://www.skylinesaustralia.com/forums/in...howtopic=101083

if so that's not giving me the info.

I need to know if 255 or wider will fit on an 8" rim.

Apart from this thread - http://www.skylinesaustralia.com/forums/in...howtopic=101561

one person's suggestion is not something confirmed. also note that entering 8"* resulted in no search results.

thanks.

An r32 gtr came out with 225s on an 8" wheel. What Manwhor3 said is correct.

Generally, on an 8" wheel, you'd fit 225s or 235s.

It is possible to stretch 205s on. This will give firmer sidewalls.

It is also possible to fit 255s on, but I wouldn't do it. It will actually decrease the traction around the corners. Sidewalls will be really floppy. It will look like a rounded blimp.

At the end of the day though, it depends what purpose the tyre is used for though. If it is for drag only, sidewall flop doesn't matter because you're not cornering. in this case, a 255 tyre like a bfg drag radial would be good.

But for cornering, I wouldn't do it.

Of course different tyres will look different, but they will stick over the side of the wheels. I have a set here in my garage with 255s on it and I absolutely hate them.

I'm not really using these wheels, but the moment I need to, i'll be sticking 235s straight onto them.

I'm not theorising. I've used about 6 sets of tyres over the last year on different width wheels. I seirously reccomend 235 as the width. As I keep saying you can fit on any size tyre. 235 is a good fit.

If anyone actually knows about tyres, you'll know that wider does not mean more grip. Increasing the width of a tyre does not increase the size of the contact patch. Contact patch is determined by factors such as weight of the car and tyre pressure.

Inccreasing width merely changes the shape of the contact patch. Making it wider rather than longer. This gives it more lateral traction. HOWEVER by having it wider than reccomended, the sidewalls flop, thereby decreasing predictability and decreasing the speed that you can go through a corner, thereby taking you backwards in terms of performance.

Fit the right size tyre and you will love it.

On an 8" rim, i'd probably fit 225/235 for general applications.

Also, different tyres will sit differently on the rim due to their shape and construction. So just because Manufacturer A says that a 255 tyre will sit on an 8" rim doesn't mean Manufacturer B will.

Most non-useless tyre manufacturers will have a wheel fitment guide for their tyres. There's generally a 1.5" range for each of their tyres, but that's not always the case.

From my observations of the manufacturers' web sites, 255 width tyres have a minimum rim width of 8.5".

    • Dear folks My family members have 4 different cars : Triton 2015 and Corolla 2011 and Mazda3 2012 and Hyundai Elantra 2014 Looking to buy engine oil funnel spill free What I found are are below  https://www.amazon.com/gp/aw/d/B0BBTTJNKX?ref=ppx_pt2_mob_b_prod_image&th=1 https://www.ebay.com.au/itm/145553221359?srsltid=AfmBOoqYBU6Ptw0LU_bAp_k67U3qkF97HHvePkA7iHZw8vUmiwoIRaRr https://www.amazon.com/gp/product/B09X23TCS5?th=1 Is there a funnel with attachment that fits most cars ? Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
