Will 5.78" backspacing be too much?

I have a chance at picking up a set of 20" BBS RW-Truck at a steal. They are 20X9 with a 20 offset. That puts the backspacing at 5.78". I'm looking to wrap them in 285/50s. Will there be any rub issues on a stock TRD Sport with no lift? Has anyone ever ran a set of these on a taco? I've seen other tacos with them in the 18", but never a 20".

 

What about if I ran 265's instead? I'm negotiable on the tire size. Just trying to see if I could make this work.

 

I'm looking to get the Enkei Deep Six 20" wheels. Same size, almost same backspace. I was told by 2 tire shops that without a lift, 265/50 20's are the biggest I can fit without rubbing or taking off the mud flaps. Hope this helps.

 

Out of curiosity, I checked the specs on the 18's. Exact same width and offset. I've seen on other tacos in the 18's. It looks like the tire size is what will make the difference.

 

And here is my answer.

It seems KPT is running the 18's on stock suspension.

Thanks gentlemen.

 

Mine are 18x9, +10 offset, which is 5.4" backspacing.
5.78" might be pushing it. I would test fir them if possible.

 

Well, it didn't even matter. After closer inspection, I realized they were model# RW014. That model has a 78mm center bore.

Oh well. I digress.

 

Yep that's the chevy version. You need Rw016 or rw018

 

i put 285/50-20 cooper zeon ltz on my 07 tacoma and they rubbed very little. nothing minor trimming or a 1 inch spacer couldnt fix.(with enkei deep 6 wheels)
