How to choose tires for the 2016 buick lacrosse sport-touring

The 2016 Buick Lacrosse Sport-Touring ships from the factory on 235/50R18 tires mounted on R18 wheels. Only one approved fitment is documented for this model year, so replacement options should match the original size exactly unless a plus-size upgrade is being considered. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.

Tire choice on the Buick Lacrosse comes down to three trade-offs that matter more than brand loyalty: load index (must equal or exceed the OEM number), speed rating (must match or exceed the placard), and UTQG treadwear (higher means longer life, lower usually means stickier rubber). Owners replacing factory tires with the same compound class, for example all-season for all-season, generally see no change in ride characteristics or fuel economy. Switching categories (performance summer to all-season touring, for example) is where the trade-offs show up at the contact patch.

For 2016 Buick Lacrosse Sport-Touring owners considering a plus-size upgrade, the safer option is a Plus-1 step (one rim size up with a 10-point aspect drop and ~10 mm of additional section width). Plus-2 is technically viable on this chassis if the alternative-sizes table lists a Plus-2 candidate within tolerance, but expect a meaningful ride-harshness penalty and a tire-cost premium of 30–60% per tire relative to the OEM fitment. For winter use the recommended pattern is one width step down (e.g. from a 235 to a 225) with the aspect ratio bumped up to preserve overall diameter; narrower tires apply higher contact pressure per square inch on snow, which translates directly into shorter braking distances. The plus-size calculator evaluates any specific rim step against this OEM size.

Before purchasing, verify the tire size on the driver-door placard of your specific 2016 Buick Lacrosse Sport-Touring, since trim levels and option packages can shift the original fitment from what is documented here. The placard reading is the authoritative source per FMVSS 110, and dealers will reference the placard rather than aftermarket catalogs when validating warranty claims.

Malfunction of a cooper CS5 Ultra Touring tire 245/4519. I noticed that the PSI of front drivers tire was low. Put air in tire, one week later the PSI was low again. I was vacationing in the mountains, so I started down the mountain to go to the nears gas station for air. I had driving apex. 2 miles when I heard the sound of a flat tire. I had to pull over on the side of this narrow road and wait for road side assistance. This was very hazardous since my car was in a blind spot to on coming traffic. When I did make it to a tire center, I was told the tire was not repairable because the belt had separated from the tire. Now this morning I have a second tire that needs air. I will get this tire checked immediately. This tires have low mileage on them and the belt should not be separating. Cooper dids to recall this tires. Incident 10/28/2022

Frequently asked questions

What size tires fit a 2016 Buick Lacrosse?
The OEM tire size for the 2016 Buick Lacrosse is 235/50R18 mounted on R18 wheels.. Trim levels and option packages can shift the original fitment; confirm against your specific vehicle's driver-door placard before purchase.
What is the bolt pattern of a 2016 Buick Lacrosse?
The 2016 Buick Lacrosse has a 5x120 bolt pattern with a 67.1 mm center bore and M14x1.5 wheel studs. Bolt pattern is consistent across the model generation; confirm against your existing wheel before fitting aftermarket wheels or adapters.
Can I run a different tire size on my 2016 Buick Lacrosse?
Plus-sizing (larger rim, lower aspect) is possible within ±3% of the OEM overall diameter per the ETRTO safe-fit standard. The Compatible alternative sizes table on this page lists every safe option for the OEM size. Always confirm with the manufacturer or a qualified tire shop before deviating from the placard.
Where can I buy tires for my 2016 Buick Lacrosse?
Online tire retailers in our affiliate network carry every size documented for this vehicle. Use the Shop online buttons above to compare prices across them; variance of $20–$40 per tire is common between merchants. The <a href="/tools/tire-install-cost-calculator/">install cost calculator</a> estimates the out-the-door including mount, balance, TPMS, and disposal by state.
What is the recommended tire pressure for the 2016 Buick Lacrosse?
The cold-inflation pressure is printed on the driver-door placard of your specific vehicle and varies by trim, tire size, and loaded vs unloaded condition. Typical OEM front and rear pressures fall between 30 and 36 psi for passenger trims and 32–40 psi for SUV/truck variants, but the placard is the authoritative source.
Can I fit winter tires in a different size on my 2016 Buick Lacrosse?
Yes; the standard winter-tire fitment pattern is one width step narrower than OEM (e.g. 225 → 215) with the aspect ratio bumped up to preserve overall diameter. Narrower tires increase contact pressure on snow for better traction. The Compatible alternative sizes table includes any winter-friendly options that fall within ±3% OD for this vehicle.
How often should I rotate the tires on my 2016 Buick Lacrosse?
Every 5,000–7,500 miles is the typical OEM recommendation for passenger vehicles. AWD vehicles and high-torque trucks benefit from the shorter interval. Documented rotation history is also a tire-warranty prerequisite; most manufacturer treadwear claims require rotation receipts at the warranty inspection.
