Looks are deceptive, rubber has hardened and there are some fraying on the sides, so have decided to get them replaced before next highway outing. Issue is availability, only MRF and Ceat available for this size, hopefully things will open up and we will get some more better options for road tyres in stock size. Yes they are balanced every time when we go for alignment.

I would suggest the following:

1) Change your tyres. I recently changed my tyres to Apollo Apterra AT2 and very satisfied with it. Coopers are the best for onroad and offroad use, but currently not available in India, as imports are poor now.

2) Get your wheel alignment done from a good reputed place with latest Hunter machine, which can align all four wheels.

3) Don't oversize tyres eg. 285, unless you change your rims also. Oversized tyres on original Ford alloys also cause uneven wear.

He said Madhus right - that’s bhpian Nikhilb’s tyre store in Bangalore and they are the leading distributor of Hunter equipment (+ a major Michelin dealer) in South India.

The 285 tyre at least provides a rather better ride quality I must say. Worth a try especially as the cheaper stuff like MRF and Apollo in stock sizes doesn’t last very long either.

285 on stock Ford alloys is not a good combination. There are many reported cases of uneven wear of tyres and the tyres bulging out. I'm very happy with Apollo Apterra AT2 on stock size, although I wanted Coopers.

Same experience with Michelins as well? What was the alloy recommendation by the way (what PCD etc) to take 285s?

There is nothing to do with the brand of a tyre. Michelin is anyway a soft compound.

PCD for the Endeavour will remain the same - 6 x 139.7. Its the offset (negative or positive) available in different alloys, that usually make the difference.
The point is that 285 mm. size tyres on alloys designed for 265 mm., make the tyres bulge out. So to compensate for that you have to overfill to reduce the bulge.

There is a reason that every manufacturer offers a standard size of tyre and wheel rim on a particular car. That’s because the car’s wheel and tyre sizes have been chosen to balance between the performance dynamics, fuel efficiency, ride and handling. So if you change from the standard size, one or all of these qualities will change.

The wider tyres with more traction might reduce the car’s top speed. Acceleration might be affected due to the increase in weight and greater traction. This will affect the vehicle’s fuel economy.

If you prefer lighter steering, think twice since you’ll need to put in more steering effort. Also, remember that your speedometer and odometer will not read correctly.

OK, what is the offset you recommend then? I haven't seen any perceptible ride and handling difference, and a 265 vs 285 section is barely 3% in terms of difference. So when I keep the speedometer pegged at 100 I'm clocked at 102 by a cop eager to make tickets.

I have used 285 on endeavour and had no issues. No bulges or anything different. Never filled any different from recommended too as the unit is PSI.

Caveat- I removed these in less than 1000 Kms for entirely different reasons, so don’t have any long term feedback. If you have from any first hand known, please do update here so others can take informed decision.

Yes, but the same car can have different sizes based on the variant or even country where it’s sold. Everest in Australia comes with options from size 17 -20 if I recollect.

Not on Endeavour surely, I don’t think I noticed anything different. With Electric/ Hydraulics small upsize should not matter.

As mentioned by ruzbe before, you should not worry about PCD unless you are also changing the alloys. If that’s the case, buy one that matches the original PCD and don’t get spacers. But for 285, I will stick with original rims unless there’s any other reasons for looks or damage.

The vehicle is regularly aligned at Madhu's and readings always has been within spec, with only very minor toe correction that was needed.

If you suspect something is off with the wheel alignment, talk to Rajesh at Vijay wheel alignment JP Nagar, his technicians should be able to diagnose and fix it. Stock wanderers are done by this mileage, may as well replace it.

Inside shoulder wear can be a camber out of spec, generally ignored by alignment shops as depending on the model of vehicle it may need shims installed after removing the suspension control arms.

Is 285 the max width the stock Endeavour tires can take? I recall one of the technician from Ford recommending 265 or 275 but can take upto 285 though he did not recommend. Similarly in Innova I have seen few guys go upto 235 on stock 16 inch alloys, though I think recommended is 215. I am guessing going beyond recommended might impact suspension in longer run but the body on frames are built to take the abuse and may handle the extra load.

You will surely need to update the tyre pressure (and maybe experiment) to find the ideal pressure for a smooth ride when you upsize tyres. I've found that 32 on all tyres seems to be ideal instead of 30 on all tyres for normal load on a 265 tyre

I am not sure if anyone noticed this, but when you are at 100 as per the speedometer, the actual speed is 5% less i.e. 95
Therefore, difference of 3% will still keep it less than reported by the speedometer.

That is a deliberate safety margin. But other than that there is extra speed from a downward sloping road, wind at your back etc (ok wind is not as much of a factor in an endeavour)

I think people have even fitted wider in Australia. I used to check Everest forums and some guys have posted pictures. Don't recollect the exact size.

PSI from wiki- It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

If we increase the area, the volume of air getting filled will be more than a smaller size but we don't need to change the PSI. A simple example can be a comparison of a bicycle or scooter tyre with a larger Car or Truck tyre. To achieve 30 psi in a smaller tyre, we will need much less air to fill than to get the same psi on a larger truck. ( Hope I am correct as usually, am not good with these things, so please correct if my understanding is wrong )

I agree with experimenting, usually, a small drop adds to the comfort.
