Mixing different tread depths and/or brands of tires can cause the unsteady feeling. also, worn tires can stick to the ground better that full tread depth tires. similiar to race tires having little tread.

    tires usually require a 600 mile break in period to help release the agents used in the release from the mold in the manufacturing process. the "y" indicates the maximum speed rating of 186 mph, or if the "y" is in brackets () it would indicate speeds of excess of 186 mph....usually found on premium vehicles like the bmw.

Can i change p245/65r17 for 265/65r17 on my envoy xuv 2004

Yes you can their just a bit wider ,which should be ok but please do check the speed rating at the end like 88T or 91V ect as if you have the wrong speed rating on the tyre it WILL FAIL THE ANUAL MECHANICAL INSPECTION ,also a long run up the motorway can cause the tyre to overheat and blow out .

Welcome to fixYa !

you might have the rear bush problem cause it handle the cars smoothly, ... moreover check the rims sometimes RIMS get curvy or erected( i dont have the word for it right now , meaning = bends) by jumps or bumps( or even if you cross a speed-breaker in high speed) that causes wobbling .. more over check for EXCELS. sometimes EXCELS cause these problem .

do write back for your problem is solved or did it remain unsolved !!

VW Passat Estate on Alloy wheels with 235/45/ZR17 tyres. want to find winter tyre suitable for 16 inch steel rim for same vehicle. Steel rim is marked 61x2JX16H2

okay, 235 is the tread width 45 is the profile(the distance from the wheel to the road)ZR is the speed rating(over 120mph)17 is the wheel to get the same tread width 225 would fit(cheaper than 235)45 needs to be thicker cos of 16" not 17" wheels and 1"=25.4mm 75 would be the choice.because winter tyres are designed for speeds less than 70mph "R" would be suitable.
all together 225/ 75(or 85) R 16.....SNOW TYRE/WINTER TREAD.

I'd definitely check the fuel pump, had a similiar fault with mine, all seemed ok until upon closer inspection there was a hairline facture around the inlet pipe on the pump which was drawing in air and losing the pressure in the fuel system

Recommended tyre pressures (touring) for 1987 Corolla FX

There should be a sticker on your door, or door post, or glove box, that tells recommended pressures. I'm guessing 30 to 35 psi. When in doubt, I go few psi lower than max. stamped on tire to start, then back it down 2 psi or so at a time until I get the ride, feel & handling that I like, then I watch the tread after a good drive down the highway. Dark on outside edges of tires, lighter in middle,air too low, add 2 psi at a time. Dark in center but lighter on outside edges, too much, remove 2 psi. & retry. Good ride, good handling, tread same all across, bingo, then I note it. Add few more pounds when carrying full load, back off to my notes for normal driving. Ride feels rougher than normal over bumps, lower it 2 psi. etc. etc. etc.

Tire Noise

This could be a combination of things. I'll suggest them and see how you go.

The tyre pressures have the most effect on road noise. Strangely there is more transmitted noise when tyre pressures are correct. Under inflation cuases a cushioning effect, whereas over inflation can make the tyre profile balloon reducing road contact.
Check that they are in limit.

Tyre tread profile can produce a humm if there are straight lateral bars. Good designs use offset bars to reduce this effect.

Cover any loadspace, and ensure sound deadening panels are in place.

Shock absorber top and bottom bushes come in different relilliancies. Hard provide tighter handling - but allow more road noise, soft absorbs noise, but allows more roll.
These bushes harden over time - thus transmitting more noise.

Shock absorber seals can swell enough to make a shock "sticky" - thus transmitting more noise.

Other suspension bushes likewise harden and become more solid with age.

So, - If it is bothering you, Check tyre pressure and condition. Cover loadspace with sound deadening material - A rubber mat in the boot works wonders.
Inspect rear shocks for wear/ corrosion.
Remove and replace bushes with new.
Replace shocks with new if required.
Inspect suspension bushes, & replace if cracked or perished.

This should solve the problems for you.
