Hey, new to the community as I bought a used 2016 IS300 F sport series 3.

My question is I require winter tires and got a good deal on a set of 4 (same) steelie rims/tires specification at 225 / 40R18. Will this fit my car because I'm hearing issues on brake clearance with the f sport.

Also does the front and back need to be different set of tires?

Thank you and hope to contribute to this community for years to come

The front and rear have different tire sizes. Front is 225/40R18, and rear is 255/35R18. If you plan on getting your own wheels, you could run 225/40's on all four corners.

As for the steelies, I don't know that those would clear the brakes. The offset would have to be such that there's space between the rim and the caliper.

Well it's a deal on wheels and tires together. What's the question I should ask the seller? Or should I post a photo?

I'd recommend the specs of the steelies are signed-off by a tire shop or our resident fitment expert @Sasnuke

So it sounds like all four steelies are setup for 225/40R18 which is fine... But, the offset would be the issue for clear calipers. I would guess you need a certain amount of positive offset.

He says that the previous car that the wheels were on was a 2017 IS250 AWD F sport,

Edit: (but there isn't an is250 for 2017 :/) let me double check

armanivnn

It's 35mm offset.

He won't take it to tire shop for verification. I'd have to buy it and do it and risk it not fitting.

EDIT: he has verified with an auto shop he got it from. It's 35mm offset

Maybe it was a 2015 IS 250 AWD F Sport... or else a 2017 IS 300 AWD F Sport.

Sounds like it should be fine.

The IS250 has much smaller brakes than the 300/350/200T, so basically anything will fit it...literally. I was using 16" rims for my 250 in winter before I upgraded the front brakes.
The IS250 come to an end in 2015 as the last year it was offered.

As for 18 steel wheels, I'm not saying there isn't a set out there that can fit, but they have to be very specific.
Since I have the same front brakes as you, I found a used set of 2IS OEM 17 inch wheels for cheap and put 225/45/17 tires on them.

If you can post a pic it would be easier to tell if it might fit.

armanivnn

This is the wheel. As said before it's 35mm offset

Sasnuke

Absolutely will not fit.
The offset, at this point, is irrelevant and the shape of the face of the rim will not clear the calipers.

Thank you Sasnuke and arentz07 for the useful responses to a potential useless purchase!

If the dude wasn't willing to take it to a tire shop for verification and on top of that said it was on a "2017 IS 250".. 2 immediate red flags. I wouldn't have wasted another minute speaking to him, just for your future dealings. Stay safe!

armanivnn

Haha red flags indeed, Swaagin. Thank you

By the way, any Canadians drive all season during the winter with the OEM F sport rims? I think I need new tires and wondering if I should get summer and winters or just all seasons.

Sasnuke

I think it comes down to where you are in the province versus what type of driving you have to do in the winter.
If you lived in downtown Toronto, I'd say new all seasons would probably be fine short of a snow storm.
If you live in Thunderbay, I suggest a pickup truck in 4x4 mode and snow tires, and chains, and sandbags in the bed, and praying to whatever God you believe in lol!!

In this age of work from home, if you can avoid the really bad snows for being on the road, some new all seasons should do just fine.
Of course remember those are the same tires you'll be using for spirited driving in the Summer.
Also consider how much selection there is of all season tires in the staggered tire sizes the IS uses.

I always use Summers and Winters...but I did do one Winter with All Seasons on my 2014 Highlander when I first got it in Feb. 2016 (off lease return to dealer) and the tires had $29K on them...and we didn't die, so that's a positive!

I am currently running summer tires here in December... If it gets below freezing, I just don't drive the Lexus. Of course, here in ATL it rarely gets below freezing or at least not for long. I am curious how January and February will be.

I do think a good set of all-seasons, performance all-seasons at that, would give me more confidence driving in the winter. Different temperature scale, but same problem. Summers are happy all the way down until about 40 degrees F, but beyond that, I don't want to find out what will happen if I push the car. Similarly, good all-seasons should do fine until you have actual snow. I drove my 2016 IS 300 AWD in snow with all-seasons, but I will say even swapping from the OE tires to something better was a huge step up in snow performance. So, some all-seasons are going to be better than others, too.
