15 inch vs 16 inch
g'day folks.
my rn130r, she's powered by a 22r, tho she's complianced to run 16inch rims n tyres.
She's running 15"s tho n they were on when I bought her.
Is the reason a power issue ie are 16"s with big tyres too much for a 22r?

stock size wheels and tires has proved to be the most effective for me. Oversizing makes the truck so slow and seems taxing on the motor. For a street vehicle anyway. obviously offroad toys need big wheels.

Let me see if i have this straight. You have 15s and you want to know if you can go to 16 and be sluggish (or more sluggish than you already are with a 22r).
Lets assume that your 15s are the factory steel rims, since you didnt specify what rims you have. Lets also assume you'll keep the same size diameter tire when you go to 16s. If you choose a typical aluminum aftermarket or even factory aluminum 16" rim, it will be lighter than your steel 15" rim. So you would be better off with the 16" rim in that case because you would have less rotating mass, again, assuming same diameter tire. There are other factors involved, but this is just generalized.
As highonpottery said, it mostly comes down to tire diameter.

thanks for yr advice guys.
mustn't be clear what I've asked...
basically wz unsure why the previous owner of my 130r downsized to 15" rims when the ol girl is complianced at 16".
the current rims are alloys, perhaps the weight factor is the reason.
thanks again.

Some people like the tire selection avail on a 15" wheel. For example a 15x31" is a common size. Of course you can get very close to a 31" tire on a 16" wheel but some people have more tire choices with 15" wheel.

what size tires are on your 15s? since alloy wheels weigh less than steel, you're basically already running the lightest wheel option and this is not the problem.
What do you mean by saying your "130r is complianced for 16"?
all pre-1995 pickups and 4runners came with 15" wheels. 16" was not even an option until the Tacoma and 3rd Gen 4runner came out.
also - what exactly is the power problem you're experiencing? since you weren't the person who changed wheels/tires - how do you even know there is a decrease in power and it's not "normal"?
