My new wheels for my polo :)

[Diesel_vert]

You'll get it with a 225/35 though right? That's a more common fitment for that wheel.

A standard load 225/35 R18 tyre will have a load index of 83.

An extra load 225/35 R18 tyre will have a load index of 87.

does anyone run 225's on a 6R? I'd have thought you'd need a lower offset for that width in the front. Rears are more likely to fit.

llai8501 has, at this point in time, indicated the only issue appears to be rubbing at the rear with 225/40 R18 tyres.

i have run 225's... My (Ronal) Aristos (18x7.5 et38) originally came with 225/45 at the front and 235/(45?) at the rear. On the sports pack springs, the fronts would scrub over nearly every (moderate) bump in the road. with nothing at the back unless fully loaded with people. i currently run 215/35 84Y (Kumho ku39), lowered on kw v1 and have not experienced any more scrubbing (except, again, in the rear when loaded with people). running a lower load rating is not to much of a worry for me, considering tolerances, if i am over the load slightly, it is highly unlikely to cause a catastrophic failure. and in regards to roadworthy, if i am defected i still have the boavista wheels (sports Pack) to swap on to clear the defect.

but thats just me and my 2cents

Ah i see, thanks man, you've been a really great help. Really appreciate it.

Thanks for your input man, So if you're defected (ive never been defected before), i can just switch out the wheels to my old stock set to clear that?

18x7.5 rims run 215/35 wheels without any issues? (aside from from you mentioned).

I dont have my car lowered, its all stock, so i'm hoping if i run the 215/35 (with a lower load rating but will be a more correct fitment) that it shouldnt scrub at all? Given that i have almost no scrubbing now unless i go over bumps and have people sitting on the back on the 225/40's?

I say this only as i'm worried that 225/35's (although beter than 225/40) may still scrub, where as the higher load 215/35's wont scrub but i'll be under load?

Thoughts?

as far as im aware. like you, i haven't been defected before.

a perfect fit

a narrower tyre will add clearance, as will a lower profile both together will give maximum clearance (as far as im aware). 215/35 will clear everything. but keep in mind the stock springs will have i lower spring rate, meaning easier to compress (someone correct me if im wrong there) so there may still be rub but only when loaded with 3 big people in the back.

I say this only as i'm worried that 225/35's (although beter than 225/40) may still scrub, where as the higher load 215/35's wont scrub but i'll be under load?

215/35 is 3mm bigger that stock, 225/35 is an extra 7mm. As i haven't had experience with the 225/35 i cant say it wont rub, but will definitely rub less than the 225/40. Another thing to consider is the off-set (et.) of the wheel as this will change the position of the wheel inside the wheel well. (my rears are spaced 10mm for an et of 28 and scrub on the outside arch not the inside of the well)

i hope everything is covered and not to confusing

(please, everyone, correct me if im wrong on any of the above. i would like to think I'm an aspiring wheel whore, and always happy to be corrected and learn from my mistakes/ignorance)

Hi everyone,

Just an update. So i ended up going with the 215/35 tyres, they only had Kumho KU39's which were $50 cheaper than the Nitto Invo's i got, so they happily refunded me the money. They said they made a mistake and have not fitted many Polo's. They were honest which i appreciate.

They also responded promptly on Sunday when the shop is closed via their Facebook page and their separate Facebook profile.

I took some photos and added a few effects onto them using Camera+ on my iPhone, turned out quite nicely.

The ride is slightly bumpier than it used to be with the stock wheels but overall i'm very happy with the look of them, and of course $200 back doesn't hurt.

Thank you everyone for your help.

anyone know since i've changed the rims and tyres if the tyre pressure listed on the fuel flaps still apply?

Or will it change now?

I've been reading up on google but find nothing specific to the Kumho 215/35 R18.

Reading this:
Tyre pressure tips

Seems its important to have the correct setting.

I'd leave it as is - which is to say, 270 kPa (39 psi) for the front tyres & 250 kPa (36 psi) for the rear tyres (or whatever the sticker states).

You can further increase the inflation pressures if you wish, but I do not recommend going below what the sticker states.


The figures listed on the sticker are for "cold" tyres (i.e. tyres that are have been stationary for some time and at ambient temperature).

If inflating the tyres while they're warm, you should add an extra 2-4 psi to compensate, depending on how long they've been driven on.

Thanks!

Kumho Tyres replied my email!

Hi Lawrence

Thank you for purchasing Kumho Tyres and your enquiry.

I would recommend running between 38 – 40 PSI in these tyres.

More than likely the Car Manual will suggest lower but to get the best performance and handling you should run higher pressures. Lower pressures will give a softer ride.

Once you have your tyres at pressures you want to run them you can check the wear patterns on the tyres, if they are wearing on the shoulders (Outside) of the tyres it means you don’t have enough pressure if they start to wear on the middle of the tyre you will have too much pressure.

Good luck, Air pressures can be a matter of personal choice as some people want a softer ride while others prefer better performance.

Yep, running 215/40/17 with 40psi
