MF 575 wheel options

[oakleaf]

I want to increase the road speed on my 575 2wd. Its currently on 13.6x38. Would it look ridiculous on 16.9x38 wheels do you think.
Im sure they will fit as there is plenty of clearance. It has the 8 speed gearbox and top gear is hardly 16 mph.
If I did get a set of 16.9x38 how much would it speed things up by?
I know this means different rims.

If you put 10 x 16 s on the front that would sit it level with 16.9 x 38 s ,roughly speaking you would gain just under 2 mph we ran the 590 s on 18.4 x 34 s that gained approximately 1 mph with them .

Im doing the same on my 398, should go to 18.8 mph instead of 17.5
That's from 300 series leaflet

That would be from 16.9x34 I presume. Which I think are about the same height as 13.6x38.

Open the revs up on the pump a bit , did that with our 565 years ago still going and we advanced the pump about 2 mm went much better and faster on the road pump set at around 2300 high idle .

Good idea too. It barely gets to 2100 at present. What direction do you turn the pump?

We opened up dad's 690 to 2500 rpm, 25 mph now

If it has a loader don't do it
Won't grip worth a light

No loader. Grip did cross my mind though so maybe pump a better option than wheels.

Taller wheels will improve grip

I don't agree, larger tyre will have more tyre in contact with the ground

I know for a 590 with 16.9/38 PAVTs on the back and although it has 10/16 s on the front the bloody thing don't grip

Surely depends on how much tread is on the tyres and if they are radials not the diameter.

That’s because it’s a massey

Yes it has so much power the tyres can't cope

we use to run the old 290 at 2500, never hurt it

Oh I see what you did there

Buying another set of rim's and tyre's is a big outlay for 1-2 mph, just open the rev's up to 2500 rpm and start saving up for a 50kph tractor.
