Largest tire that can fit in spare tire of 2017 LX570 (1 Viewer)

[prez1967]

Previously lifted my GX460 and could no longer fit my spare under the car.

Dont want to make the same mistake on the LX

Whats the largest tire that I can fit on the factory 20" wheels that will still fit in the spare tire location?

34ish

I'm planning on getting a 275/65r20 for my spare. 34" diameter

My 295/70r18 fits in the spare location like a glove. Every tire manufacturer varies in actual tire size, but this size on the calculator are 34.3" and mine are Toyo RT Trails. I would make sure you get actual sizes from the manufacturer.

There is enough room for up to a 34.5" diameter tire to fit underneath.

awesome! Thanks for the quick responses!

Looks like a modest 33" will be just fine.

Could/is there any modifications I could do to fit kenda 35x10.5r17 (34.7"). Panhard relocation bracket or something?

with enough cutting and welding you can do whatever you want.

any issues with fitting 275/60/20 or 302/55/20 on factory 20" wheels? Any rubbing, etc that would need to be massaged? will I be able to use the EZ exit function of the suspension for when my wife drives truck and move around a parking lot in low until it raises?

No issues.

I've had a 305/55R20 in the spare for many years. Currently have a 275/65R20 in the boot.

As was said earlier, anything less then 34.5" diameter will fit just fine. The wider tires may stick down a bit more but nothing of concern and still leaves a ton of clearance for serious off-road. There is room in the spare hanger bracket to space it up 3/8" on the frame brackets if desired.

Now if one installs an LRA aux tank that pushes things down 1", that'll have to be considered in the width of tires stored down there.

Tanks for the info!

I understood about the spare location having plenty of space. Good to know about the LRA tank.

Was debating staying with 20s or going down to 17/18s. Want to ensure that there will be no rubbing in daily use with whatever setup I pursue. 20s would be easier/cheaper but Im curious how much softer the ride would get with 17/18s

I saw this post, so I need to also ask, how many mods did you need to do to fit 295/70/ R18 on your truck? I am about to change my setup on my 2017 LX570, as I still have the 21" wheels on it.

I run this tire / size spare underneath.
But I have an OEM sub tank which pushes the hang point down a couple inches
And my spare is a used tire with about 10/32 tread.

My wheel offset is +25. With that, you will need to do just work on the fronts.

The fender liner needs to be pushed forward. @TeCKis300 has a detailed explanation and illustration on how to do it. You will also need to remove the mud flap and bend the bracket out of the way.

To get rid of any mild rubbing while reversing, you will need to take a heat gun to the rear part of the front fender line and use a 2x4 block or something of that nature to reform the liner a little for more clearance. TeCKis300 covered that also.

It's a pretty easy mod.
