225 35 20 OR 245 30 20 tyres for 20 inch wheels VY S2 04?

[James]

Hey everyone,

What would be a better fit for 20 inch wheels? 225 35 20's (can get required load rating) OR 245 30 20's tyres?

This is for an 2004 VY S Series 2, and have 20 x 8.5 Chrome Alexis gestalt rims.

I also want to lower my car by 50mm or so from stock height sometime soon. Currently stock height.
Just need advice which tyre is usually better than the other , etc.

Thanks everyone.

245/30R20 would fit in my opinion, a bit more tyre on the ground is nice, slightly more traction. The 225's will be cheaper, but you have a very limited range of tyres to choose from with the correct load rating, pretty much only Achilles ATR. So my vote is 245/30R20.

245's will most probably rub... I had 225, and 235's on my car and both didn't rub, as soon as I got 245's it rubbed

No offence, but not really a helpful post. Depends completely on your car/suspension setup/wheels - maybe your wheels have a lower offset.

Sorry your royal Majesty!!

Start off by going here Tire size calculator

Whack in ur current tyre size, the drop in 2 sizes ur looking at and see which one keeps within rolling diameter and won't affect ur speedo.
Yes yes u can get a speedo corrector, but that's another cost

How was your post helpful without listing what sort of car/suspension/wheels you have?

Thanks everyone, more people with their opinions would be much appreicated.

I put in the tyre size calculator to see how it would effect my speedo and results came as :

225/35/20's
Speedometer reading is 2.0 % too fast. 60.0 mph = 61.2 mph

245/30/20's
Speedometer reading is 0.4% too slow. 60MPH = 60.2 MPH

So the 245's are obviously better for the speedo? not much difference anyway.

And if they do rub i can just roll the guards? My vy is stock height currently but as stated before wish to lower by 50mm from stock height.

245's hard to get a load rating for, alot of tyre places around me don't do them unless they're expensive tyres.

225/35's also protect more from potholes - then again you don't plan on hitting one like I did :S...


Being a VY, whatever choice you make if you're that fussy you can go Holden and get them to re-calibrate it for $90. I did it when i got my Diff gears done .


I honestly would prefer the 245/30's though, you can go lower on them as they aren't as high, my 225/35's scrub on the front wheel arches on super lows on (big) bumpy corners. Not alot, but it does happen now and again.

But once again depends on the offset as Sweefu has suggested.

Goodluck - Either one will do fine, 225/35's will be cheaper though.

Edit: Just a tip, When i got my 225/35/20's fitted on ultra lows (about 60mm lower than standard) if i didn't get my guards rolled at the same time i wouldn't of been able to drive without chewing out the tyre. I suggest getting the rears (or even fronts - but they mainly rolled themselves slowly) rolled before lowering.
