$650 Per Tyre? Need Your Help!

[Seano350GT]

Your local tyre joints should be able to fit and balance for 15-20 a tyre if you supply the tyres. You should find Kumho cheaper than that if you shop around, We do Jap Nitto's for that kinda money, and Achilles fair bit cheaper, We dont sell the Kumho so cant help on those but they should be a fair bit cheaper than 366 a tyre.

245 35 and 275 30 20 is ideal.

(EDIT: can help get you the Kumho a fair bit cheaper if you like, just pm me.)

Pm'd you mate.

[Seano350GT]

that's a decent price you got on those.

Just to answer your question, its fine to be running the 245/35s on your fronts and the 275/30Rs. I ran that particular profile setup in the 19s, threw off the speedo by about 5km/h (100 on speedo, actually doing 95)

See i realllllllllly don't want my speedo to be out, i will avoid that at all costs. I have 3 points left

If all else fails paget discount Tyre and battery should be able to fit and balance the three. Not sure about other places fitting and balancing tyres that didn't come from them, doesn't hurt to ask

Ali should sort you out anyway

haha true, I just saw what 100 was on my satnav and matched it with needle position on speedo.

If in doubt I just had my satnav on and switched back and forth if i needed to change songs lol

So i was just speaking to a mate in the states that has the same lowering springs, same size rims, same car, and 245/35/20 F 275/30/20 R. He says that the speedo shouldn't be off because when you do the calculations the fronts are within a cm from the back diameter. He didn't explain it very clearly but he has never had any problems with speeding or anything because of it, but in saying that he hasn't checked if his speedo is off. I don't have a GPS and i would love to get 245/30/20 from somewhere hopefully this guy Ali K can help me out

Remember to compare stock wheel size against the ones you want or have..the speedo is calibrated for stock wheel and tyre sizes.

And its the rear sizes that matter as this is where the speedo gets its reading from on the gear box, unless Im old and things have changed.

Thanks A LOT for this, it says my speedo will be off by 2.11km p/h. Is it possible to get it "balanced" or something so that my speedo is corrected but i can still run those tyres?

[The Bogan]

I believe its possible but I would just stay slightly under the limit.

The word you are looking for would be "calibrated", you would need to get the speedo re-calibrated.

[S T A R 3 3]

you bought 20 inch rims and youre only just worried about tyre prices now?

Lol.. this. I did the same thing tho

Ah calibrated then. Who can do this?

[Commsman]

Ah calibrated then. Who can do this?

If the V35 is anything like the M35 (& a lot of other cars btw), then the speedo is intentionally made to read non linear. It might be an attempt to stop people speeding, or maybe to give owners an unrealistic idea of how fast their car is. Below is a graph I did a while ago on tyres with rolling diameter the same as factory.

It raises some question as to how a speedo would be calibrated to fix the non linearity - it looks like a compromise might be required.

[Seano350GT]

At the moment it appears i'm just going to have to drive a few KM's slower. Ah well.

Just get a satnav or something and see how far your out with the new tyres. You'd be surprised how quick you learn what your actual speed is compared to your speedo

My power fc hand controller is actually pretty close to actual road speed so i just go off that

And are you sure you can't get a width/profile tyre that matches or is slightly under your rolling circumference of stock tyres? Surely if you go 10mm under or something you can find a good combo

I do plan on upgrading my sound in about 2 months so until then i'll just have to drive a couple of KM's under the limit which is okay. ATM my stock tyres are 225/40/18 245/40/18. If i go for say, 245/40/20 the speedo actually goes off by a lot more nearly 4km i think it was. 245/30/20 & 275/30/20 is probably the closest combo i can find that LOOKS great on the car and fills the guards really well and only goes over the limit by 1.8km p/h.

255/30R20's should work well on the rear, only .73km/h difference at 60km/h

Remember you only need to look at the rear wheels for your speedo difference.

However, if your car has traction control, then you may have issues if the rolling circumference is different.

I'm not sure on the deal with this is

Did you hear back from Ali (Taleb Tyres)? He is pretty good at working all this out, if you ask him what the best match would be he should be able to sort it out. I did next to no thinking when I got both sets of wheels/tyres off them, Ali Picked good offsets (there not aggressive but I'm not into mexican looking wheels anyway) and a good matched set of tyres. This is why I reccomend them to people, because they are good at what they do and really nice to deal with

I think i'm going with 275/30/20 on the back, it says when i'm doing 60 i'm actually going 61.94 so i'm okay with that.

I know guys that have 275's on the back and have no issues with VDC at all so that's good for me.

Yeah been sending messages to eachother all morning very helpful so far and actually told me that my car's manufactured with 225/45/18 245/45/18 instead of 225/40/18 245/40/18 they just cheaped out on compliance haha. He's sorting out prices now with some Kumho KU31'S i'm just unsure about if i should go with 225/35/20 or 245/35/20 at the front.

[89CAL]

Personally I'd go slightly under size, the KU31 grips well so shouldnt be a problem. The slight stretch looks good without being rediculous

My old ones were about 10-20mm undersize for the rim, think they were 10. Looked pretty good:

Thats just me but. Whatever your back tyres are doing (stretch or bulge) I would keep it the same up front

Update:

Purchasing a set of Achiles ATR Sports off Ali K @ Taleb Tyres

225/35/20

255/35/20

Going for a stretched look on a 20x8.5 and 20x10 rim.

He's helped me out loads on information about fitment and especially price!
