Should i replace all four tires at once?
Hello,
The front tires on my IS350 are in need of replacement but the back tires have around medium tread left. Should i replace all 4 tires or just the front and then come back and replace the back after they are more worn down? I have not owned a vehicle that had different size tires in the past so i am not sure how to go about this since the back tires still have plenty of tread.
Thanks.

Personally I'd just replace the front tires and wait for the rear tires to wear down, there's no point in throwing away perfectly good rubber. I'd advise for rotating the tires but then again the iS350 is a staggered setup. It's good practice to get the same model/brand of tires that you had before, whether you want to get a wider tire that's up to you, but it'll keep the handling characteristics of the car the same and balanced.
I have been on a different set of front and rear tires for a while now. Just as long as the front and rear tires are within the same category, you'll be fine. What I mean is all of the tires should either be all seasons or high performance summer tires etc etc. AND of course the front two tires should be the exact same tire.

2010 IS250 -For me, had the same issue fronts were bad, rear tires were in okay condition. The front tires on the IS wear down much faster than the backs. The same issue came up on the 2nd time replacing that the rears were fine but the front tires were way past due. I change all 4 no matter the condition, since were gonna pay for alignment and all might as well take care of the tire issues in one big Leap. IF my rears are good and the fronts look well worn, I would ride that mug until its bald in the front or until a puncture by nail forcing you to buy new tires. The better deal comes in when buying all four All Season tires, rather then spending money for jsut two. Cheaper at First, but in the long run its a time saver and you cant beat 4 new vs 2 new. Look at it in the big picture when you have other errands to run and you just dealt with replacing t2 front tires a few months ago, now your back again replacing the back. Feel me now? Plus LeXus deserves the best so all 4 is the way to go. 
Just replace the front tires. Replace the rears when they are worn. Tire are expensive, you're just throwing away money by replacing all 4 at the same time. My rear tires wear out faster than my fronts, and about I about to replace the rear tires and leave the front alone.
The real answer is - It Depends. It depends on how you drive and what you expect out of your car. For the average Joe, replacing tires in pairs per axle is fine. For the performance enthusiast who expects more, and installes max performance tires, than nothing less than four will do. Me, I replace all four in both my F and my truck when two on either end are worn. But, that's just me.
For the OP two would be just fine, but be sure that the new replacements are the same brand and model of the tires you are leaving on.

Should you do just two on any end and the tires you have can not be matched brand and model, look at side wall and tread construction as well loading. Try to match old tires.
Although any tire may get you down the road, when you go to set the car for those sweeping turns a miss matched set is taxing as both ends of the vehicle will have different side loading characteristics. That said tread squirm on matching tires from treaded to half tread can be less than enjoyable too.
Last comment; the door name plate for tire pressure and loading refreneces Max capacity = max cold pressure.
For those of us clocking most miles as driver only the rear pressure is likely too high and over time you'll blow the centers out. Adjust the pressure accordingly based upon wear and how YOU drive/use the vehicle.

If staggered then do the fronts unless it’s miss matched. If so either match them or get new rubber all around. My staggered Bmws I’d go about 25k miles on rear and 35k up front. All were same tire. You paying for a premium experience and might as well get it. Tires matter. If money matters more rethink what your doing.

I personally have been running the Michelin Tire Pilot Sport A/S 4 All Season tires for over a year and about 20-25k miles and they are amazing. In the summer they grip perfectly and are exceptional for spirited driving. In the rain they are just as great, I push the car in wet and slick conditions and I've never once lost traction. They are also great in the snow. (I live in NJ so I see all types of weather and temperatures) I have never had an issue with them and I am extremely happy with them. They are a bit pricey but I think it's the best all-around tire!

I have different sets/brand on my is350, performs well in snow, rain, summer...
The fronts were purchased at Tire Discount and the rears at Walmart, and they were cheap to.
Almost no spinning from a dead start, and my is has a tune FBOs (PPE headers, exhaust).
I would give the rear tires a rotation/balance, have the shop check em out for any issues.

I have summers & winter tires. Assume the summer tires are from when the car was CPO'ed in 2018. I will check the dot code and brand next time I swap in March-April.
As for Michelin Pilots, I am getting them for my Celica. Very happy to hear they are good tires.
