Just grabbed 4 Pirelli scorpions (255/50/20) from the bay. Used, but described as all 5-6mm tread. No puncture repairs and even wear.
When I bought my car a month ago it had two Toyo's up front and two brand new Nexens on the rears.
I have an issue with some budget tyres, at least all the ones I've ever bought - the sidewalks always bulge out and it appears as though the tyre is under inflated.
I am going to have the tracking checked as the Toyo's (up front) appear to be wearing on the outer edges. I appreciate the mass of the vehicle and this could also be attributable to cornering forces.
Has anyone else had this issue with Toyo's or is it more likely the tracking?
I'm expecting more from the Pirelli's as they are considerably more expensive.
Luckily the 4 cost me less than one new one collecting them tomorrow.[/u] 
Had it, loved it!

The Pirellis sound like a good deal  .

I number of possible things to consider. ( I have the pirellis and they are good )

THe load rating between the 2 tyres may be different. I've found that the load rating has a fairly big effect on how thick the sidewall is and consequently how much it bulges. I hvae a pair of Kumho KL12 and Kumho Solus in the garage and same size, different load rating, notable difference in sidewall.

Outer edges on the front tyres have always worn most on my L322, looking at other tyres, it seems fairly common on other larger 4x4s when I see them too. I think that also depends on how much cornering you do as well. V8 or else ...

I'll ask the same question I always ask then. Have you done the chalk test?

All tyres have different characteristics depending on construction methods, materials, rubber hardness etc. The correct pressure for one will not be correct for a different make.

How to get the right pressures then? Find a quiet level piece of road, preferably a dead end on an industrial estate or similar. Inflate tyres to a known pressure and check with an accurate gauge. Mark a line from one side to the other, right across the tread face of each tyre (ordinary blackboard chalk will do fine).

Drive gently about 100 yards and inspect the chalk lines. If they are even then the pressure is good. If they are fainter at the edges the pressure is too low, and if fainter in the middle, too high.

Adjust until you get it right. And if it sounds like too much effort, well it's your tyres. I run Scorpions cos I like them but I'm now on about 28K miles out of this set with an even 3.5mm left all round. Plenty of people I know won't use Scorps due to poor life. That'll be wrong pressures then

Thanks fisha they are the correct load rating for the car.

Mzplcg - don't suppose you want to share the pressure you use, if indeed your running 20" wheels, this would be a great starting point for me? Thanks.

What pressures do you recommend for Scorps? I just got a set of Scorp Zeros and they are amazing, but I want them to last for a while since they were pricey!

Already asked this question further up, maybe its a secret?

Worth noting LR build in a safety margin with their door pressure sticker and it also assumes a near full car. I run mine at a little lower than Door Sticker especially in winter. Chalk test is good idea.

I fear that a chalk test might be tough since we're flooded here and my valve stems are prone to snapping

I used to have 22's on a pimped hilux and loved toyos. Under heavy driving I got over 40k on the fronts and 30k on the rears. Appreciate FFRR is a totally different vehicle but was going to change to toyos on the SC because of previous experience 07MY SC VSE (on its way)

The list of previous cars is long & some are boring there has been two RRC's and a very pimped hilux
