Tyre Width - Noticable Difference?

[evil_weevil]

Hey Team,

I have been waiting for a while for my size semi slicks, but nothing yet, I now have 10-20% tread left and I need tyres before my next sprint round.

So my question is, I know I'll be losing 20mm of track - but overall, how would it effect my handling? is it going to be different in anyway, shape or form??

do I just wait and hope my supplier can get the 205's before mid October (50% chance!!) or take the gamble and get the 195's ?

(this is for my mx5, not a skyline too )

Cheers,

Chris

You won't lose any "track" - that is controlled by the wheel design, specifically the offset.

So I doubt you'll notice much difference at all in handling with 10mm less rubber width.

[evil_weevil]

well, its a total of 20mm as 10 each side - as long as I dont loose time or places I'll be happy

[Duncan]

yeah unlikely you will notice the difference. and for sure a good tyre 10mm narrower will still handle better than a wider, worserer tyre.

in fact for supersprints you may find it improves times as they will come up to temp a little quicker, and may not go off with a short run

Cheers Ducan!

what about say a max, 10 lapper race?

Give hornibrook tyres a call and see if they can get your size.

I recently picked up some new re55's for 380 a corner inc shipping, which isn't far off the 340 i paid for r888's at taleb last time.

I'm not sure if the pricing was specific to the size i bought but it's worth a shot regardless.

Same weight, same track, smaller footprint. Of course the difference will be noticable for sporting applications.

They'll also "go off" quicker.

depending on rim width the 195's may be preferable

[mad082]

if you were to be using the same compound tyre etc, but 10mm skinnier then there is going to be a difference on performance. and it won't always be bad, but there will be some negatives. overall you are losing 40mm of tyre (assuming you need the tyres for both front and rear). which is nearly 5%

negatives of skinnier tyres:

less traction off the line

less grip when cornering and braking

go off quicker

positives of skinnier tyres:

less rolling resistance (faster acceleration once traction is no longer an issue and higher top speed)

lighter (again, faster acceleration) (yes i know that the weight difference will be minimal but every little bit helps in a race)

come up to temp quicker (so more grip earlier)

^^very good points mad082.

interested to know what the rim width is though...

Hi everyone.

Was about to post a similar question but hope it's ok if I ask it here.

Im looking at a set of 18" rims, 8.5 front, 9.5 rear, that come with tyres 245/40 front, 275/40 rear.

I understand that to fit in my guards I have to look at getting smaller tyres, 225/40 front, 245/40 rear. The tyres I'm looking at don't come in 245/40, only up to 235/40.

Would it be ok to get the 235/40 for the rear? I have an r32 gts-t 4door. I don't do any aggressive driving, mostly daily driving to work and highway kms as well.

Thanks for any help.

i would have suggested a 235/40 anyway mate, it will be fine for sure.

Thanks for that Michael
