I run 10/12psi on the rear, but mine are GoodYear radials, grip like something else. When I swapped from x ply to radial the traction difference was very significant...
Narrow tyres or normal tyres

Very posh to use Good Year tyres. I only buy cheap Malhotra tyres!

I find that the tyres I've got are quite good grip wise, they are 11.2 28 and are kleber traker, and they weren't to expensive either.

Ha ha....the tyre maketh the tractor!
10% more footprint gives 10% less ground pressure (lb/sq inch). Unless you add 10% more weight to compensate for the larger tyre the frictional force exerted by the tyre is exactly the same as the narrower tyre and thus the tractive force is the same.

I run superkungs, they have a tread pattern similar to good year super traction radial, nice gap between the bars, and not really deep tread, and tyres grip best when half worn

I run Agribibs which are radials but with a tube in. Grip is phenomenal but they don't make them in 28's any more.
The thing to bear in mind is that the plough will not function correctly unless it is pulled correctly.
Avoid at all costs tyres where the tread bar widens substantially toward the centre. As Bob so rightly says the more contact that the tyre has with the ground then tractive effort is proportionately less.
In the late 60's early 70's Firestone did an F151 which had wide tread bars at a flatfish angle and fairly wide spacing. At the time these were the best ploughing tyres as they did not cut the ground up as did deep and narrow tread bars set at a steep angle. The downside was that they were lethal on steep wet grassland. Firestone discontinued these in England but never stopped making them in the States.

Would anybody only buy a certain type of tyre brand or do they buy any old crap that is cheap?
Radials seem to clean well but beware using tubeless on older tractors because the rims are often not in the best condition and you will be forever pumping them up. I had a battle with mine and tried Slime sealant applied to the beads with little success but then got some pink coloured tubeless sealant made for badly corroded alloys and this has worked wonders. You have to push the tyres off at the bead and apply generously with a spatula or small scraper. I use my diff lock very frequently to reduce surface disruption and think it is the biggest asset with light tractors.
Returning to tyre width, I have watched a ploughmen using rowcrop narrow wheels and they pull as well as anything under normal conditions but there is an obvious disadvantage in very soft ground

I'm afraid to differ, the increased footprint means more tread contact, which equals greater soil shear, which equals greater tractive capability.

I wouldn't by cheap crap. IMO many a good tractor restoration is ruined by crappy cheap tyres.

now then, just to throw a spanner in the works, in vintage the tractor has to be in production per 1960, befor radial tyres came out, so the question is, should radial tyres be allowed ?

Yep your right, but there is no ruling on it that I know of...

The foot print probably isn't that far apart. A taller tyre of the same width will have more ground contact and less rolling resistance.

Don't buy a tractor off me then!

I got a bleb in my 12x32 bought from a chicken dentist but found a pair of 8x44's for £50. Need to run them at 2 bar behind my 7.50x16 fronts for an interesting season.
A company called Alliance made a similar pattern tyre to the one you have mentioned, I have been trying to get a pair of either no luck yet though ?

now then, I really dont know about modern day Alliance tyres, but in the 80s early90s were i worked we had a couple or tractors on them, not the wide low pressure ones, more like older style of tyre, but if the new ones of today are the same, then I would never want to find a pair ever, as on contracting, they did not grip well at all, and would keep away from them,
saying that, i have had no experience of newer ones in that make as after mid 90s we never had anymore
Perhaps better to stear clear of them then, was an advert on e bay for brand new Firestone's last year wished I had got them now
