Difference Between Low Profile Tires And Other


seejaylk

Recommended Posts

hi..

can somebody explain what are the Difference between Low Profile tires and Other (i dont know the name) and what are the pros & cons of Low Prof tires..?

thanks in advance...

Low profile tires have short side walls

Pros-low profile tires makes the ride stiff,improves handling(Cornering) and improves steering response

Cons-It reduces ride comfort and has more strain on the Suspension system (Wht ive heard)

If you dont travel on rough roads much go for it :)

I'm running 17 inch goodyear EF1's with 40mm profile

Pros

1.Improved handling(good grip,less wobble etc)

2.Better water treading,but this veries from tyre to tyre

3.Good looks IMO

Cons

1.Uncomfotable

2.Decreased fuel efficiency

3.Price

4.Can eff up your suspension system

5.More chance of damaging the inner/outer wall,my two left tyres busted when I entered a pothole at moderate speed,so I had replace both at 17k a pop.

6.Can confuse your speedometer and mileage meter if the original tyre diametre ratios are not retained.

Quick question Don. Why less fuel efficiency? If the tire width and diameter stay the same, why would there be a difference?

well machan if you want to add low pro tyres and still retain the original diameter at the same time,you have no choice but to increase the rim size...and unless you put in those light weight rims,they are quite heavy,so more weight more fuel...

but your somewhat right...the profile itselfs effect on fuel efficiency is minimal as far as I know.

Yeah, unless he meant the wheel weight factor

totally! even if the biggers wheels only weigh a coupla kilos extra at each end it affects the performance quite a bit thanks to the increased rotational mass and inertia. usually the theory is the increase in rotational mass is 10 times higher as opposed to fixed mass. so if you get wheels that weigh 5 kilos to replace ones that weigh 8 at each end on a 4wd car like an impreza that's similar to a weight reduction of 120kgs.

damn, mine weighed 15kg with tires lol, say tires would weigh 5kg? Would they be it too heavy for normal 1.5l sedan? :D

it IS! thats nearly 10kg for the wheel alone. mine are 7.3 each and i feel even thats too heavy for their size. anything around 5kgs would be ideal. its better to stick to 15"s for a car that size.

Interesting stuff. Didn't really think it'll have that much difference, but good points.

i believe it makes a noticable difference. i adviced a friend to shop for lightweight wheels and he ended up fitting 5kg wheels to his 121. his car weighs 80 kilos more than mine but when we run i can't seem to shake him off even though we got the pretty much the same engine setup and almost similar gear ratios. and he confirmed the car feels quicker after the wheel swap.

very true jadey...when i was in the market for a set of bigger alloys I tried on a normal 17" set and the car felt REALLY heavy...but after i got my current set which are lightweights,it is massively better...but it s still considerably heavier from the original smaller set.

i'm no expert --maybe the answer is the increase in weight.

but i think - it could be because the tyre grips the road more than normals. when it happens IMO - i think since there is more resistance for the vehicle to go forward [maybe initially -at a standstill only]-

came to this conclusion -when i changed from 13 to 15 - i installed low profiles - the tyres were picking up sand particle and splashing it against the mudguard - more than before.

Guys,

adding 2 quick questions.

Currently I' running on 195/55/R15

Travelling 40% on rought roads (really uncomfortable) .

1. What is the best profile size for me ?

2.What will be the maximum profile size that I can go with out changing rim size.

Thanks In advance.
