My truck calls for 285/60r20e tires. Can I put 275s on instead? Many more choices in that size and style cheaper.

Yes merely you volition run a piddling college rpms at same speed you usually would with tires you lot have now. I don't think it would exist that big of a deviation tho.

275 is the width of your tire, which ways it is 275 millimeters wide. I doubt 10 mm of width will brand a divergence. Depending on what the attribute ration (2nd number) is, the tire may be the same meridian as the 285 and non touch the speedometer reading.

Width x attribute ratio = rim to tire border
Rim to tire border x 2 = diameter minus rim (metric)
Diameter minus rim x 0.03937 = diameter minus rim (inches)
Diameter minus rim + rim diameter = total diameter of cycle

285 x 0.half dozen = 171 x 2 = 342 x 0.03937 = xiii.46 + 20R = 33.46" bore

275 10 0.6 = 165 10 2 = 330 x 0.03937 = 12.99 + 20R = 32.99" diameter

Your speedometer may be slightly lower at loftier speeds only you probably won't notice much difference.

If the modify is to a smaller diameter (more revolutions to travel the aforementioned distance), wouldn't that make the speedometer read a higher speed than the vehicle is traveling?

No. But the contrary. A bigger tire has a higher linear velocity than a smaller ane. And then y'all volition travel further with larger tires spinning the aforementioned number of times.

its best to keep the same outer diameter so speed and gearing doesnt change any

I went with 275'south instead of 285'south and oasis't noticed much of a difference. There are tire comparison calculators that tell you lot what size you can change to and how information technology affects rpm and mileage. I but found a tire size that was close to what factory specs are and what the dealership put on. The 275's were much cheaper.

For what it's worth, I don't tow much or go off road. I do use my truck to haul lumber for building furniture.

Whatsoever issues with running a load range d instead of e?

Truck is a 2015 ram 2500 4x4 diesel. I have a boat that is about 10,000 lbs. only merely tow it from the shed to the launch, almost 3 miles. No other towing for the most role.
