New Tyres

[Sputnik]

Hi all !

 

Just got a set of 215/45/17 today and found that I need to rev harder to pick-up and somehow feel that the power isn't really being transferred from engine to tyres.

 

Is it normal for new tyres to take some time before they can become "stickier"? Which I feel is most likely the cause of my drop in pick-up.

 

Cheers !

wat kar do u have? and wat is the stock size ...

[Mondeost220]

wah...17inch...215..kinda big if ur car is 1.6L...

Galant 2.0 VRG

 

Was using this size previously and don't have any problems so far. The stock tire was 15".

Might be the rims + tyres are heavy...thus causing the drop in performance. When upsizing, try to keep the weight of the rims down as much as possible so as not to affect performance.

[Mondeost220]

fuel consumption would definitely increase..but cornering ability wld be considering lowering your ride?

[Sputnik]

Am still using the same set of 17" rims, just that with the change of tires, the feel is different from my "seasoned" tires.

 

Yeah...could definitely save some fuel if I use lighter and smaller rims. Still manageable at around 9.5km/l (Galants ranges from 8-11km/l). Cornering is indeed stable, but this is one car that isn't exactly that fast even with mods.

 

Yes ride is already lowered.

wah u change from 195/60-15 to 215/45-17 ... sure look but performance sure suffer since u +2

 

new tyres maybe got more grip/drag perhaps - what tyres were u using b4 and what tyres did u change to?

 

maybe 205/45-17 would be less draggy?

Could be the tire weight or the air-pressure. New tire is thicker than old, so heavier. Underinflate tire will be draggy too.

 

Just my 0.02 cts.

I agree with Assassin.... very likely the weight of your rims and tyres. What rims/tyres did you get ? My own experience when I switched rims (both 17") but same tyres, found that a 1.5 to 2kg difference per rim made tons of difference.

[Modeldriver]

believe the weight of the rims are probably the bigger culprit than the additional 20mm.

Try waiting until after the scrub in period to see if it changes for the better.

[Sputnik]

Scrubbing ... learnt this term from my friend today. New tires take awhile for them to take effect, and yes Day 02 saw a marked improvement.

 

P.S : Again, I did not change rims, just tires only. I have been using the 17" rims for a year already. Already used to the consequences of heavier rims !

Performance tyres weights 1-3 kg heavier than norm tyres. Checkout Sept Motoring , it featured BS Pontenza S-03 PP and Pirelli P3000 Energy.

 

The Continental PremiumContact and Pirelli P3000 Energy got a weight diff of 2.3kg for a 14" tyres. A 15" S-03 weights 9kg.

yep.... but I thought the scrubbing was more for enhanced grip ???

I am not surprised that Sputnik felt a loss of power after his tyre change .

 

I had the same feeling after I changed my tyres recently .

Straight away the car felt sluggish .

I had changed to a higher performance model tyre with better grip.

I can feel the big difference in the rolling resistance of the tyre when I push the car .

Scrubbing will not make you regain the lost power , infact it should be even worse as the tyres can now grip even better .

 

As the saying goes , U can't have your cake and eat it .
