SR5/TRD wheel compatability

Here's what I'm considering doing but wasn't sure of all the options so looking for a little feedback/experience. I've done research, but not too familiar with all the tire/wheel nuances so hence the basic questions, I'll apologize for that now. Also looking to invest as little as possible...
I've got a '12 DCSB SR5 4X4, with stock rims/tires. Happy with them, but also like the fatter look of the TRD OR BFG's, which is what I've had on trucks in the past. Live in upstate NY, 80% of driving is highway commuting, about 22K/yr, comfortable with winter driving on stock tires. Not looking for/interested in a lift/upgrading to serious offroad or signif larger tires/wheels; wouldn't mind if the truck sat a little bit higher with slightly bigger rims/tires if possible, but not a necessity. Offroad use is typically work related (fields, logging trails, occasional moderate recreational off road, camping, ect). Also towing various sized trailers on a fairly regular basis.
I'm considering a few configurations, including picking up a set of used rims (either TRD's or SR5 stock steel) and having a set of dedicated rims/snow tires (never had snow tires before, have done fine without them, but a little extra traction never hurt anyone).
With the stock rims on my SR5, are there larger/wider tires I can get without signif sacrificing quality of tire, ride, mileage, road noise???
Can I simply put a set of TRD OR rims on my SR5 without needing further modifications? One option is having a set TRD rims and a set of SR5 stock rims and having snow tires on one set and all seasons on the other and just swapping the myself at the change of seasons. If this is doable, is it better to have the wider tires on the TRD rims be the snow or all season tires?
Thanks

 

Yes, You can put TRD rims on a SR5, no different whatsoever. As long as it's a 6 lug. I know a few have dedicate snow sets to use in the winter vs not winter.

 

random question to add to your thread ( thread jacked) are trd sports speedometer calibrated for the 17 in wheel or does it matter going from a trd OR 16 to a trd sport 17 make that much difference?

 

The wheel size wont effect the speedometer, only tire size which are pretty much the same on all 6 lugs.

 

No problem, don't have an answer about speedometer calibration but don't know if this helps as far as how much of a difference a change in tire size will make:

Thanks for the response; yes they're the 6 luggers....

 

If you are up-sizing your wheels/tires so that the rolling height/diameter will be larger than stock, then your speedometer and odometer will be off. For example, I put 285/75/16 on my truck and when my speedometer says I'm going 60...I'm actually going 65. (according to the tire calculators I've looked at) This is the fix for it right here

 

As long as the wheel/tire diameter is the same. In simple terms larger wheel+smaller tire = smaller wheel+bigger tire.

 

^yup

 

Narrower tires work better in the snow than wider. The narrow tire cuts into the snow while the wider tires float on top. Run a 245 75 16 snow tire for the winter on your junk wheels and a 265 70 16 all season on your trd wheels for the summer.
