Tyres For Isuzu Slx/Sx....Or Colorado

[FlorC]

Hey, I 'm driving an Isuzu low model, so 215 R70 15. More than 76.000 km in about 3 Years. About time to change the tyres, looked on websites, in the shops and read the older post here on TV. There is some choice, Bridgestone R611 like on all the new

low Isuzu's , Dunlop grandtrek PT2 , Vantrek V1, Comfort lm 703, The Michelin ones , Goodyear and Maxxis has some nice ones. They are all around 3000 to

3200 B , Maxxis some 500 B less.

Now which to choose? The thai or malaysian websites are not very clear for good information, even if it is in English.

I drive in cities and the highways and smaller roads, try to avoid dirt roads and gravel and broken concrete.... Rain and dry weather.

1) the size , 225/70 or 235/65 can do, they are wider, more grip? They are a little bigger , so lower rpm for the same distance.

2) patern of the tyre , for minimal spray of rain water (and muddy water!) and shooting little stones that are everywhere on these dirty roads, against the carbody, and of course the noise .

3) Is there really a difference in fuel consumption , between wider tyres and different patterns?

I am quite happy with the original Bridgestones 623, and always around 35 psi, but in comparison with other cars, that do have nearly perfect round tyres,

mine were always somewhat sagging even pumping them up to an onconfortable 40 psi.

Which tyre are you happy with?

It there a price difference between the Bangkokal area and up north or far east?

What are your views?

Thanks

1) 225/70R15 will be 2% larger than stock, but well within limits. 235/65R15 will be the same diameter as your current tires, but with larger contact area (better grip).

2) Minimal water spray = minimal water dispersion = minimal wet road grip.

3) Yes. Larger contact area = more grip = more resistance = less fuel economy. OK, OK, compounds also make a difference, but this is a good enough guide when talking about light truck tires.

your biggest cgoice will be to go either "heavy load" like the michelin vanpix, xcd, the dunlop vantrak and the bridgestone hd tyres or go normal use.

In 215/70x15 most tyres are build for load, not for comfort.

If load is not a concern, pick a tyre you like for the looks and for the price

my 2c

for heavy duty use, with 1ton plus on the truck seven days a week, its a bit different game.

all the tyres OP mention are high load index/low comfort tyres focusing on lifetime and price only

if 600kg payload is sufficient for OPs use, I would rather look for minivantyres like Goodyear GT2 225/65-15 or larger with loadindex 97 as I recall. All the sudden pickup will have traction and be able to brake decently:)

Thanks for your replies.

I'll look into the comfort tyres.

Are the heavy duty tyres, the ones that some pickup's and SUV's get perfectly round?

If I compare stationaire unloaded pickup's or SUV's, my tyres have about 15 cm contact with the ground, the really round ones maybe 7 cm !

I drive a lot but no load , so I like comfort more than a hard ass.

The Bridgestone 623 are no problem for braking, but coming downhill fast in a bend in the road , they feel a little unstable.

very high load index makes tyre rounder unloaded, reducing contact area with ground.

To high air pressure provides same result, your tyres need approx 29-32 psi, check label in drivers door sill.

Both increase braking distance and reduce traction.

If I pump to much pressure, the contact with the ground is only in the middle of the tyre, and that is the section that gets worn.

All the tires OP mentioned are NOT heavy load, PT2 is SUV tyre, LM703 is passenger car tyre.

Now I dont know too much about tires for pick ups but it goes roughly like this

heavy duty/ heavy load Michelin XCD, Dunlop Vantrek, Bridgestone Leo 677, no comfort whatsoever

medium duty/ medium load pick up /suv Dunlop PT2, Michelin Vanpix/Agilis, Bridgestone Duravis

extra load or reinforced standard tire in these sizes: Dunlop LM 703 and some others

If not used for heavy lifting an LI of 97 and up should be fine, indeed
