i will need new tires next spring, i got 4 free tires at my job(i work for goodyear) .

Can i go with some 225-55-16 in the front and some 255-50-16 to the rear.


Do the 255's are to large for the ponys.?.

Does the 225 and 255 have the same height?

Thks.

Well I have 245/50/16's all around and they do fine....I think 255/50/16's would be just a little big for stock ponies...Those tires will probably roll alot on the corners....

I had the size tire you want only I have 205s in the front, For the rear I did have to remove the quad shocks, and roll the fenders, I now have 245/45/17 and I spin all the time, I miss having fat tires, I have to drive slowly now to avoid spinning, maybe it's just the cold...

Yeah the cold weather had a big effect on my traction....in the summer I could take off from 5 mph and it would just take off and go.....but now I can't get traction till 60 Darn the cold weather

Wheel Height..

Hy there... U can calculate the tire size yourself... 225-55-16 225:100=2.25 2.25*55=123.75 123.75*2=247.5 16*25.4mm=406.4 247.5+406.4=653.9 653.9*3.05=1994.395 Okay, this is: 225-tirewith in millimeters 55-fiftyfive percent of tirewith is the height of the tire 16-the rim size in inch. So, the profile is 55 percent of the tirewith=123.75mm The rim size is 16inch, thats 406.4mm, and the wheel diameter is 123.75*2 =247.5mm plus the rimsize, 406.4mm, thats 653.9mm. If U will know the wheel rolling diameter, one turn (circle) use 3.05 instead of 3.14 (because U will loose some mm because of the airpressure/flat ground pressure...) So the total circle of this tire is 653.9mm*3.05=1994.395. The other tire is 2017.27mm THEN, if U are using a3.73:1 ring gearing, standard tirecircle multiplyed with the gearing,devided to the new tirecircle is the actual ring gearing. Your eksample is ,1994.395 *3.73 :2017.27=3.687. It is normal to use approx. plus/minus 5 percent of the standard tirecircle.... Puuuhhh... good luck.

The "Pony" wheel is 7" wide. The maximum recommended tire size for that wheel or any other wheels that is 7" wide is 225mm (8.9"). You can go wider than 225mm but the tire will not ride or handle optimally.

Tire width shouldn't be more than 2" wider than wheel width. Tire manufacturers recommend specific tire widths for specific wheels. So do vehicle manufacturers. They don't make such recommendations for no good reason.
