Massey 1250 Tires

[tj200]

Hey Guys,

I did some searching around and have come up with a formula to calculate the tires that I could run 0-5% front tire lead.

(front rolling x 1.6077771) / rear rolling

subtract 1 and mult 100 to get the ratio.

I have a question. I have bald turf tires right now.
Front= 212 80 D15
Rear= 355 80 D20

I was wondering if I could get away with keeping my turf tire and run ag rear and R4 in front

run firestone
front= duraforce dt tl- 215 70 D15- 7 inch rim width- 79 rolling
rear= radial 4000 tl r-1w- 360 70 R20- 11 inch rim width- 126 rolling

After my calculations that gives me a .8% ratio (which is perfect)

But I was wondering if these tires would fit. It is hard to get an exact rim measurement. ( I have googled until my eyes hurt) Does anyone know how wide the turf rims are? I am hoping my time spent on the firestone site along with the calculator will pay me off. (keeping my current rim combo)

My op manual (1240/1250/1260) says you are not supposed to mix R4s and R1s (assuming you have 4WD). It lists your R1/AGs choices as 12.4x24 (rear) with 7x16 fronts or 13.6x24 (rear) with 8x16 (front). If you want to go with R4s your choices are 15-19.5 (rear) with 25x8.5-14 (front) or 14.9-24 (rear) with 10x16.5(front)

The manual implies but doesn't state explicitly that the 13.6x24 (rear) with 8x16 (front) combo fits on the same rims as your turf tires.

Hope this helps!
Jeff

Unfortunately the front rims are 15 and the backs are 20. Arent your tires in the front R4? And your rear are R1?? I was looking for the same setup as what you have and some others that I seen.

I wouldnt mind even having all r4? tires in this picture. I pm'ed the guy but have got no response. If someone could help me out and tell me what size these tires are that would be awesome!

I have R1 (AG) front and rear

 

[tj200]

Really? For some reason I always thought r4 are the squared off tires like the ones I threw up in the pic??? and like the ones you have in front.

I don't really know what the difference is - I'm just going by the manual which lists my fronts (8x16) as R1.

Awesome,

Hey Jeff thanks for your support in this. It is confusing. I will do my best in getting the pictures over to you when it stops raining
