Check a different size against this vehicle

Type any tire size below — we'll compute its overall-diameter delta against the OEM 175/70R13 and verdict using the ETRTO ±3% rule.

Common upgrade paths

Plus-1: 185/60R14 — one rim size up, 0.42% OD change. Sharper steering, mild ride penalty, modest cost premium.
Plus-2: 195/50R15 — two rim sizes up, 0.14% OD change. Noticeable ride penalty, higher pothole risk, meaningful tire-cost premium.

Use the plus-size calculator to evaluate any rim step against the OEM size.

How to choose tires for the 1993 Pontiac Lemans Base-Model

The 1993 Pontiac Lemans Base-Model ships from the factory on 175/70R13 tires mounted on R13 wheels. 7 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.

Tire choice on the Pontiac Lemans 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 1993 Pontiac Lemans Base-Model 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 1993 Pontiac Lemans Base-Model, 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.

Frequently asked questions

What size tires fit a 1993 Pontiac Lemans?

The OEM tire size for the 1993 Pontiac Lemans is 175/70R13 mounted on R13 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 1993 Pontiac Lemans?

The 1993 Pontiac Lemans has a 4x100 bolt pattern with a 57.1 mm center bore and M12x1.5 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 1993 Pontiac Lemans?

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 1993 Pontiac Lemans?

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 1993 Pontiac Lemans?

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 1993 Pontiac Lemans?

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 1993 Pontiac Lemans?

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.
