I am sort of with you in way. I can see the point of having staggered wheels, if it gives the rear wheels a greater dish than the front (for looks).Why do people fit wider rims / tyres on a van? I guess purely looks? From my perspective and my motor racing experience it has zero advantage to any handling characteristics. A van on a really good suspension set up with narrower rims and 40 /45 profile tyres will handle way beyond most drivers capabilities on the same size all around. Comfort is always compromised with really low profile tyres and wide rims that are not designed for a van in the first place. I love to see the show vans they look amazing. Each to their own. Enjoy
However I don't get the wheels that are staggered but look exactly the same face on. For me that is just carrying extra weight of wheel and tyre around for no benefit. Looks, comfort or performance.
What goodyear tyres are these
Goodyear Eagle F1 Asymmetric 6’s.
How you finding them ? Thinking of getting a set when current set need changing.
Compared to the original 275/40R20’s the conversion company fitted to my van, these in 245/45R20’s are light years ahead. The drive, overall handling and road noise are miles better. Would recommend them.
I’ve only had my van since the end of March this year. Always had hot hatches prior to the Transporter, so know only too well that you need good tyres under you. My wheels are only 8.5J and I soon learnt that 275 tyres are too wide for this width of wheel, that being said, a lot of conversion companies still fit them. My original tyres were brand new when I bought the van, but the road noise and handling was horrible. Yes, I know it’s a big heavy van and not to be compared to a hot hatch, but after changing the suspension to Bilstien B14 Komforts, I noticed slight rubbing on full lock, especially in reverse. The new tyres have made a massive difference and I intend to use them on the van all year round. I don’t fly around in the van, but having a narrower and better tyre on the van has made the steering more precise and the overall driving experience worth the expense.
Excellent review fair play
Little advantage is provided by having overly wide tyres and rims, handling is very likely to be worse. There will be greater forces, leverage acting upon the steering gear tending to pull and disturb smooth running. Moderate dimensioned tyres fitted on the recommended rim width for the tyre size is the best policy and preferably in the middle sweet spot. Tyres fitted to rims that are too wide and outside of the recommended rim with recommendation, are a danger and could rapidly deflate with less provocation. They can also be awkward to reseat. For most comfort and best handling probably a mid size wheel diameter and width would be closer to the best that can be achieved for all-round benefit. Using tyres from the top manufacturers is generally preferable and give the best results and in the long term the higher price on purchase will be paid back in better handling, feel and grip and most probably last longer too.
So far as fitting different wheels of different size front to rear my guess is that it is not the best policy for the vast number of vehicles. True Ferrari, Lamborghini etc do but have been designed that way from the start, many of these machine do not stray too far from the high street in any case but also need expensive tending. Near all of them rear wheel drive and produce large amounts of power while under power. Though it is a puzzle why the front that can absorb far more power under heavy braking is a narrower fit but then perhaps it is for far shorter periods of time.
Educated guessing suggests that fitting tyres of the same size to different rim widths might make differences in tyre geometry affecting rolling circumference air volume and so on and may affect the ideal recommended tyre pressure. Having differing rotation speeds on wheels or axle pairs cannot be a good idea and even though the vehicle computer sensors may allow or some discrepancy for tyre ware it cannot be a good idea to push that artificially by deliberately pushing the boundary, who knows how that might affect a vehicle when the vehicle is driven on the edge or under emergency conditions. Perhaps it might distract the affect the ABS in some adverse way or other tipping a balance. For a similar reasons manufacturers do not recommend running with unequally worn tyres.

I'm looking to replace my 255/40/20 101 with the same size but less of a profile ... let me explain ... I've found that there is quite a variation in the physical size of different brands even allowing for wear. When I replaced my budget 255/40/20 101 with the Uniroyal Rainsport 5's they has quite a lot more sidewall and then I replaced 2 of those with Yohohama Advan sport and these are monsters in comparsion. So is there a brand than has the smallest 40 profile in a 255 ?
Nankang come up small which is why they are popular with the tuning scene as they allow for better fitment. I've ran NS2 on several cars and rate them well. I'm into my 3rd set of Accelera 255/40/20 and these some up smaller than premium brands. They also wear very well, around 30k to a set on a 100mm lowered Caravelle.
As a whole budget brands are generally smaller like for like. I guess they save on rubber!

Excellent, thanks. I have run Nankang before but on cars and yes they are good for a budget brand.
There is so much discussion on here regarding wheels and tyres. I’ll give you my ten penny worth that suits me but will be not everyone’s choice. Vehicle is a T6.1 T32 SWB Kombi.
Wheels all around are 20” x 9” with 265 40 20 104y. Tyres are Goodyear Eagle F1 Asymmetric 5. Tyre pressures 36-38 depending on load. Suspension fitted by CRS adjustable Koni dampers with adjustable spring seats. H and R springs. I find this set up as good as you can get on 20”s without going to Air suspension. Your 8.5” rims I would say are a tad too small for 265s which will cause more movement in the side wall especially on turn in. Ride quality and performance is not just wheels and tyres it’s the complete suspension set up together with premium tyres and a decent laser alignment. I suggest speaking to Steve at CRS. Good luck.

Not for a T6 or T6.1 but anyone any first hand experience of good all season tyres for 2021 Landrover Discovery. Currently had mid range tyres installed which needs replaced. Are Michelin cross climate 3 or 2 a good idea or is there any other brand anyone would suggest? Being a 3.0l V6 I'm not wanting to go down AT tyre route as would kill mpg even more. Current tyres R20 255 55 , 110W extra load
I'm in 265/40/20 all round, 8.5" front 10" rest 4Motion. I'm looking at wheels as well and I did read somewhere that 255 was the maximum (recommended) width for an 8.5" rim job.
My fronts do look a bit balloony and the rears a bit stretched ...
Have a look for Vredestein all seasons. Best I have used, had them on a few cars.
