Larger Tires Of '03 Lx470?

bmegdal · November 29, 2003

I would like to change the tires on my 2003 LX470 from the stock 265/70-16 to some LT295-75-16's that I have from a previous vehicle. I know the speedometer will then be off, but on elocal shop told me I will have terrible problems with the fuel injection, check engine lite and ABS. Is this true?

Must be wishful thinking...it is a 2001 LX470 that I want to put larger tires on.

Thanks.

Not true.

You will have no problems with fuel injection, check engine light, ABS -- none of it.

How the heck will the fuel injector know that you have bigger tires???

You might notice a bit of a loss as far as power goes -- but with the 470, it shouldn't be too bad. If you want to fix the speedo, you can get either a new spedometer gear or an electronic gadget (like the TruSpeed calibrator) to correct the speed on the spedometer.

p.s. I'm currently running 285/75 R16 and will probably get 315/75 R16 next, with no worries about EFI, ABS, ect.
